Introduction

The Institute of Atomic Physics and Spectroscopy (IAPS) at the Faculty of Physics and

Mathematics (FPM), University of Latvia (UL) was established by Resolution No. 74 of the Senate

of University of Latvia on March 1, 1994 of joining the Department of Spectroscopy of the

University and the Laboratory of Theoretical Physics of the former Institute of Physics of the

Latvian Academy of Sciences.

IAPS is active in research of atomic and molecular physics and development of optical

technologies. The competence of the staff members of the Institute in the field is recognised

authorities at both the national and international level. Fundamental and applied research on laser

radiation to determine and alter the characteristics of atoms and molecules is aimed at development

of new photonics devices. The comprehensive experience acquired in the field of spectroscopy, has

proved to be useful in research of stellar composition and Earth’s atmosphere, as well as in water

quality control, the expertise of artworks, development of new energy-saving light sources, and

improvement of optical fibre production technologies. Recently the Institute has developed

prospective optical methods and devices for clinical diagnostics and laser therapy. The scientists of

IAPS render a significant input in the study process at the University of Latvia – they are involved

in supervision of postgraduate, graduate and undergraduate research and teaching of more than ten

courses at the Faculty of Physics and Mathematics.

The present report is an insight into activities of the Institute over the decade since

foundation. A brief history includes collections of colleagues who founded the Institute and

associates of two laboratories that made the basis of the IAPS. Thematic aspect provides a short

characteristic of the seven IAPS research groups. The list and analysis of projects developed during

the decade is complemented by references to published results in scientific journals and

presentations to international meetings. The report is concluded with a review of theses

accomplished and defended at the Institute, description of the Science Board of Astronomy and

Physics functioning within the structure of the Institute, and a list of the science seminars of IAPS.

1. A brief history of the Institute

Atomic physics and spectroscopy has a long-standing tradition at the University of Latvia. As early as in 1919 Laboratory of Physics was founded at the Faculty of Mathematics and Natural Sciences. The Laboratory further evolved into the Institute of Physics (IP), headed by the Senior Assistant Professor F. Gulbis. The main tasks of IP included teaching physics at the faculties of the UL and organisation of research in spectroscopy, X-ray physics, and physical electronics. In 1930s a fruitful international collaboration in the field of spectroscopy was initiated with the University of Warsaw. The Dean of the Faculty and Head of the Department of Experimental Physics in the post-war period Ludvigs Jansons was a visiting scientist there. Throughout the time of its existence until 1944 (with an intermission 1940-1941) the Institute of Physics was part of the Faculty of Mathematics and Natural Sciences.

After the 2nd World War the work commenced in spectroscopy was continued. It developed in two directions – molecular spectroscopy and atomic spectroscopy, including applications to research energy transfer at atomic collisions. This direction became particular interest in the beginning of 1960s in the context of active media for gas lasers.

In 1967 the Problem Laboratory of Spectroscopy (PLS) was formed on the basis of the Department of Experimental Physics, and was headed by Professor E. Kraulinya. The Laboratory, as well as Problem Laboratory of Semiconductor Physics (headed by Professor I. Vitols) and Problem Laboratory of Segnetoelectrics and Piezoelectrics Physics (headed by Professor V. Fricbergs) became an independent scientific structural unit of the Latvian State University. Rapidly extending research, LSP occupied an entire building in Old Riga, 4 Šķūņu Street. In 1987 PLS formally became Department of Spectroscopy (DS) of the Latvian State University. Research of LSP/DS involved processes of elementary collisions and photonics in the gaseous phase and vapour. Modern spectroscopic methods and lasers were used in the experiments. 20 theses for the USSR degree of Candidate of Sciences and 3 theses for the USSR degree of Doctor of Sciences (E. Kraulinya, M. Jansons, R. Ferber) were accomplished and defended from 1967 until 1990 in SPL/DS.

In 1957 Dr. Viktor Veldre founded the Laboratory of Theoretical Physics (LTP) at the Institute of Physics of the Latvian SSR Academy of Science (IP LAS). Research of the LTP was focused on collisions of atoms and electrons, nuclear physics, magneto-hydrodynamics and solid state physics. LTP co-operated with the group of E. Anderson from the Computing Centre of the Latvian State University. At the beginning of 1960s the theoretical work in atomic physics was internationally recognised, and LTP became known to scientists in Western countries as the “Riga Group”. The USSR 12 degrees of Candidate of Sciences were awarded. Five scientists of the LTP - R.Peterkop, R.Damburg, M.Gailitis, I.Bersons and E.Karule-Gailite were awarded degrees of Doctor of Sciences by the University of Leningrad (St. Petersburg).

These were the historical circumstances under which the two strong scientific laboratories were formed in Latvia, and continued research in atomic physics and spectroscopy both experimentally (the SPL/ DS in the UL) and theoretically (the LTP at IP of LAS). Both the laboratories achieved international recognition. The community of physicists even coined the term of “Riga school in atomic physics”. As a result of cooperation among the scientists of the two laboratories, two large conferences were organised in Riga bringing together scientists from the entire Soviet Union: “The Physics of Electron and Atom Collisions” (1967 and 1984), and two international conferences gathered in Riga a number of Western scientists as well – The 6 th International Conference on Atomic Physics (ICAP, 1978) and The 4th European Conference on Atomic and Molecular Physics (ECAMP,1992).

In 1994, following the initiative of Prof. Māris Jansons, both the laboratories joined in a new structural unit within the the Faculty of Physics and Mathematics of the University of Latvia - the Institute of Atomic Physics and Spectroscopy, and continued successfully theoretical and experimental research of atomic and molecular systems. Applied research was developed in various spheres of optics (development of high-frequency electrodeless lamps, optical fibre and

4

optoelectronic devices, optical methods in medicine, etc.). The science of Latvia suffered immense loss due to the untimely death of the Director of the Institute, Professor M. Jansons in 1997. The Institute continued to work under the lead of Professor Marcis Auzinsh, expanding its international cooperation and area of research. In 2000 the Group of Stellar Spectroscopy headed by Dr. L. Začs joined the Institute. A significant event in the history of the Institute was support granted by the European Commission to the Centre of Excellence – a 5th Framework programme project in the field of basic research and application of nano-scale physics.

The Founder and Director of IAPS Professor MARIS JANSONS

02.08.1936 - 18.09.1997

Maris Jansons has been with the Faculty of Physics and Mathematics (FPM) in the Latvian State University since 1960. His research was guided into atomic physics and spectroscopy by Senior Lectures O. Schmit (Ojārs Šmits) and Jazeps Eiduss, and Dr. E. Kraulinya (Elza Krauliņa).

In 1966 M. Jansons began his work as a research assistant of the Problem Laboratory of Spectroscopy (PLS) led by Dr. E. Kraulinya. His results on electron-atom collisions and low-temperature plasma were reported at USSR meetings in Kharkov (1965) and Kiev (1966). His research was summarised in Thesis on “Sensitised Fluorescence in Mercury and Indium Vapour Mixture.” M. Jansons defended Thesis in optics and was awarded the Candidate degree in physics and mathematics by the UL. One of his opponents was Professor Sergey Frish of the Leningrad State University. Since 1970 M. Jansons has been teaching at the Division of Experimental Physics as a senior lecturer, and as assistant professor since 1975.

At the end of 1979 Prof. E. Kraulinya delegated to him the guidance of the PLS, in 1987 reorganized into the Department of Spectroscopy (DS). E. Kraulinya and M. Jansons had a long cooperation in teaching and research, and by that time M. Jansons had acquired experience as Deputy Dean of the Faculty, position he held for four years. In the period from 1989 until 1993 the Head of the DS M. Jansons was also the Chairman position of the Division of Experimental Physics.

The experimental work was continued, Maris Jansons gave his contributions to the international conferences on atomic collision physics in Riga and Cambridge (1969), Amsterdam (1971), Ushgorod (1972), Belgrade (1973) and on atomic physics in Berkeley (1979). His papers were published in Optika i spektroskopija (1970 – two; 1978, 1979, 1982, 1983, 1984), Dokl. AN SSSR (1978), Chemical Physics Letters (1976, 1979, 1982), Journal of Physics B: Atomic and MolecularPhysics (1982). M. Jansons supervised 5 graduates at the UL. They defended their Candidate Theses (E.Kopeikina 1977, S.Papernov 1979, J.Klavins 1983, Zh.Shvegzhda (Ž.Švegžda) 1984; S.Zagrebin 1987). In 1985 M. Jansons was awarded the degree of Doctor of Sciences in Physics and Mathematics and in 1988 the title of Professor in Optics. In 1991 the USSR Doctor degree was nostrified to the degree of Habilitated Doctor of the Republic of Latvia (Dr. habil. phys.).

The monograph “Elementary Processes in the Alkali Plasma” (Moscow, Energoizdat, 1988, 242 pp.) has been written by M. Jansons together with Andrey Klyucharev, Professor of the University of St. Petersburg. Professor M. Jansons has also collaborated with the scientists of the Polish Academy of Sciences (1979 and 1989).

A similar collaboration developed since 1973 with Professor V. Demtroeder (Germany) where Maris Jansons worked with Prof. Klaas Bergmann). In 1992, a Research Assistant of M.Jansons J.Klavins (J.Kļaviņš) stayed at the University of Kaiserslautern on DAAD (Deutsche Akademische Austauschdienste) scholarship.

M.Jansons was invited speaker at the Conference on Atomic and Molecular Physics in Riga (1992). Besides, he gave his contribution to the Conference in St. Petersburg (1992) and the Conference on Low-Temperature Plasma Physics in Riga (1993). M.Jansons was elected as Corresponding and Full Members (Academician) of the Latvian Academy of Sciences (LAS), in1992 and 1993, respectively. He chaired the Commission of Experts in Physics, Mathematics and Astronomy (the 3rd CE) of the Latvian Council of Science (LCS).

Since1992 M.Jansons had been a foreign member of the Council of Electron and Atom Collision Physics of the Russian Academy of Sciences (1992-1996). He was on the board of the Latvian Physics Society. He renewed its activities with a regular schedule of seminars and conferences, in Riga (1993, 1994) and in Daugavpils (1996).

It was his idea to establish ‘a research institute at the faculty’ by joining two laboratories: the PLS (later DS) of the University of Latvia and the Laboratory of Theoretical Physics of the Latvian Academy of Sciences (LAS). The aim was consolidation of Latvian scientists working in the fields of atomic physics and spectroscopy. Actually, it was a rebirth of the former Institute of Physics (1919-1944) that existed at the UL, under the subordination of the Faculty of Mathematics and Natural Sciences, and had analytical spectroscopy and atomic physics as subjects of studies and research. M.Jansons insisted that ‘founding of the institute would integrate education and science in practice’. On February 28, 1994 the UL Senate approved Resolution No.74 by which the Institute of Atomic Physics and Spectroscopy (IAPS) was established on the basis of the former Department of Spectroscopy.

The IAPS was launched on March 1, at the building at Škūņu Street 4 (By order No. 1/38 of the Rector of the UL Prof. Juris Zaķis). Since 27.04.94 M.Jansons was director of the Institute he had created and, consequently, he became the member of the Board of the Faculty and the Senate of the UL. He took care of the development of the IAPS and was proud of it. Initially there were six habilitated doctors, but within three years their number grew to eight (M.Auzinsh 1995, and M.Tamanis 1996). Prof. Maris Jansons was leading two recearch groups in the Department of Spectroscopy. (The head of the Theoretical Physics Department, up to now, is Prof. Erna Gailite) .

In the period from 1994 to1997, M.Jansons supervised two LCS grants – “Investigation of the Energy Transfer and Ionisation Processes in Molecule-Atom Collisions” and “Low-Temperature Plasma Studies by High-Resolution Spectroscopy” (earlier, in 1990-1993, he supervised another grant “Spectroscopic Studies of Energy Transfer and Ionisation Processes due Collisions in the Vapour Phase of Chemical Elements”). Two doctors (J.Klavins, A.Skudra) and five masters (V.Grushevsky, A.Ekers, K.Orlovsky, G.Revalde, S.Putnina) worked on the projects. G.Revalde was awarded her Dr. phys. degree at the end of 1996, after a DAAD scholarship at the University of Mainz, Germany (Advisors – Prof. G. Werth and Prof. M.Jansons). A.Ekers (LCS postgraduate student, later also a DAAD scholar) and K.Orlovsky worked for doctor’s degree under supervision of Prof. M.Jansons. (A.Ekers was awarded the Dr. phys. degree at the beginning of 1999, when Professor M. Jansons had passed). Cooperation with universities in other countries was going on: with Professor K. Bergmann at Kaiserslautern University, Germany, with Professor S. Svanberg at the Lund Technological Institute, Sweden, with Professor M.Głódź at the Physics Institute of the Polish Academy of Sciences, with Professor A. Klyucharev at the St. Petersburg University, Russia.

Main results of the research in the period from 1994 to1996 are briefly mentioned by Prof. Maris Jansons in the Report of the LAS Commission of Experts as follows: The mechanisms of energy transfer and ionisation by collisions of atoms and molecules in alkali metal vapours have been studied theoretically and experimentally (M. Jansons, V. Grushevsky). Intra-molecular perturbations of KLi molecules (A. Ekers) and lifetimes of metastable states of Na2 molecule (J. Klavins) have been determined. The hyperfine splitting and abnormalities of nuclear hyperfine structure of Eu+ ions have been determined by methods of super high-resolution laser spectroscopy (G. Revalde). All these results are of fundamental importance for nuclear, atomic

6

and molecular physics, and spectroscopy, and they can be used in physics of low-temperature plasma and gas discharge.

Professor M. Jansons was a member of the organising committee and speaker at the plenary meeting of the International Conference on Low Temperature Plasma Physics in Petrozavodsk (1995). From 1995 Academician M. Jansons was a member of the Spectroscopy Association Council of the Russian Academy of Sciences and the Section of Molecule Physics in the European Council.

Along with his many duties Professor Jansons continued teaching at the FPM of the University of Latvia, and prepared new courses on optical quantum generators, atomic spectroscopy, problems of modern physics, non-linear laser spectroscopy, and laser physics and spectroscopy. His lecture notes of the last two years for the graduate course on spectral line profiles were not accomplished.

On September 16, 1997 Maris Jansons was elected as Full Professor in laser physics and spectroscopy at the Faculty of Physics and Mathematics of the University of Latvia. Two days after the candidates for Full Professors’ positions in sub-branches of solid-state physics were assessed, Professor M.Jansons passed away.

The memory of him is alive in the Ludvigs and Maris Jansons’ memorial award to young scientists (LAS Senate decision of September 22, 1998.). The award has been granted to H. Rjabov (1999), Arturs Kulsh (2000), Olga Nikolayeva (2001), Janis Alnis (2002) and Olga Docenko (2003). The last four are postgraduates of IAPS.

A. Tale

Professor Elsa Kraulinya04.08.1920 – 07.01.2002

There is no such force in the nature that would not succumb to man’s work, provided he has chosen this work lovingly and put his soul into it. These words said by writer Lev Kasil can be rightfully applied to the lifelong achievements of Professor Elsa Kraulinya (Elza Krauliņa).

Elza (Vēvere) Krauliņa was born August 4,1920 in Sloka. In 1939 she enrolled in the Faculty of Mathematics and Natural Sciences of the University of Latvia to study physics. In 1941 the studies were interrupted by the war. In 1943 in the land occupied by the Nazis, E. Kraulinya was involved in underground publishing of newspaper "Jaunais Latvietis"(The New Latvian)‚ in 1944 she started to work in the editorial office of the newspaper "Padomju Jaunatne" (The Soviet Youth) as a responsible secretary. Later, in August, 1945 to be able to combine studies at the University and work E. Kraulinya went to work in the editorial office of the newspaper "Cīņa" (the Struggle) and continued to work there also after graduation of the University in 1947. In May 1949 E. Kraulinya focused her attention on physics and started the postgraduate (PhD) studies in the Leningrad State University under supervision of Professor Sergey Frish, Corresponding Member of the USSR Academy of Sciences.

After earning the Candidate degree (equal to Western PhD) in February, 1952, E. Kraulinya started to work at the Faculty of Physics and Mathematics of the University of Latvia, as teaching assistant (1952 – 1953)‚ lecturer (1953 – 1956), and assistant professor (1956 – 1973). She lectured on general physics‚ applied optics and spectral analysis‚ atomic spectroscopy. From 1956 to1959 E. Kraulinya was the Dean of the Faculty of Physics and Mathematics. From 1958 to 1967 she was the acting Chairman of the Division of Experimental Physics, and from October 1 1967 to April 1 1979 she headed the Problem Laboratory of Spectroscopy (PLS). From the very beginning it was clear to E. Kraulinya that a lot of things would have to be made by the personnel. Therefore, a glassblower was recruited, a mechanics workshop was established, and a strong group of specialists in electronics was assembled to build and maintain the necessary equipment.

In 1971 Elsa Kraulinya was awarded degree of Doctor of Sciences (equal to Western habilitated doctor) after defending the Thesis “Excitation energy transfer in sensitised fluorescence of metal vapour“ at Leningrad State University. E. Kraulinya was the first woman-doctor in optics in the Baltic republics and the first physicist-doctor in the Latvian State University. In 1973 Elsa Kraulinya was awarded the title of professor.

In 1978 Elsa Kraulinya was actively engaged in organising of an international atomic physics conference in Riga. In 1979 she resigned her post as the head of the laboratory and continued to work as a scientific consultant. Elsa Kraulinya has edited 15 proceedings of scientific publications of the PLS. Her journalistic skills were of great help there. She is the author of more than a hundred publications and has made contributions to many international conferences.

For more than 30 years from 1958, Elsa Kraulinya had chaired the Science council for spectroscopy of the Latvian Academy of Sciences. Monthly lectures on the news in spectral analysis were delivered for the laboratory staff of enterprises. Such laboratories were in 32 enterprises in Latvia.

Professor E. Kraulinya first and foremost was a personal example to her co-workers. She gave up a lucrative job in the newspaper "Cīņa" for studies and research‚ where the salary was too small to have proper meals, but, nevertheless, she saved up small sums to support her mother in Riga. She truly wanted to do her duty at her best: her performance becoming less than perfect, she left her post as the head of the Laboratory already in 1979. Prof. E.Kraulinya handed the post over to her first PhD student Maris Jansons. Her presence at work gave confidence that in difficult and important moments she would give a consolation or help in finding an optimum solution, and, in case of necessity, acted without any delay. E. Kraulinya always put the common interests higher than her own. May God help us to do as good as she was doing!

The Laboratory of Theoretical Physicsof the Institute of Physics of the Latvian Academy of Sciences

(1958-1993)

The Laboratory of Theoretical Physics (LTP) was founded in 1958, at the Institute of Physics (IP) of the Latvian Academy of Sciences (LAS). Dr. Viktor Veldre (1924-1967), Deputy Director of the IP, was the first Head of the Laboratory. Both Dr. P.Kunin who moved to Riga from the University of Moscow (course of quantum mechanics), and E.Riekstins (course of mathematical analysis) – gave significant contribution to teaching high-qualified physicists-theorists at the University of Latvia.

R.Peterkop, R.Damburg, V.Kravchenko (solid state pysicist), M.Gailitis and A.Gailitis were in the Laboratory from the very beginning. E.Karule joined in 1959, I.Bersons in 1960, as a researcher in nuclear physics. V.Kascheev (solid state physicist) also worked there.

The Laboratory had close ties with the Leningrad (now St. Petersburg) University. Prof. G.F. Drukarev and Prof. J.N. Demkov were frequent guest researchers in the Institute. R.Damburg, R.Peterkop, M.Gailitis, I.Bersons and E.Karule were awarded degree of the USSR Doctor of Sciences by Leningrad State University (LSU).

The main subject of research initially was collisions of electrons with atoms. The calculations of electron scattering by hydrogen atoms using the close coupling approximation, were performed by Dr. Raymond Peterkop (1930-1991), Dr. Robert Damburg (now Prof. Emeritus), and Dr. Modris Gailitis (1935-1993), simultaneously with British scientists headed by Prof. P.J.Burke. These were the first works in this field.

R.Peterkop and E.Karule improved the method and were the first who calculated cross sections for slow electron collisions with alkali metal (Li, Na, K and Cs) atoms within the close coupling

8

approximation. The wave functions for alkali metal atoms were calculated jointly with Erik Anderson’s group at the Computer Centre of the University of Latvia.

The research on atomic physics in Latvia was carried out independently and simultaneously with the Western scientists, despite the considerably worse computers available. Complicated mathematical problems were solved by original mathematical methods, which later were applied also by the Western scientists.

The papers were published in collections of: “Atomic Processes” (Riga, Zinatne, Ed. R.Peterkop, in Russian), in J. Phys. B: Atomic and Molecular Physics, and in other journals abroad and in the USSR. Collections “Atomic Collisions” and “Cross Sections for Collisions of Electrons with Atoms” (Riga, Zinatne, 1965, in Russian) were immediately translated and published in the USA. Thus the Laboratory of Theoretical Physics in the middle of sixties became known by Western physicists working in the field of atomic physics as the “Riga Group.”

In 1967, for the series of papers “Collisions of Slow Electrons with Atoms“ V.Veldre, R.Damburg, R.Peterkop, M.Gailitis and E.Karule were awarded the Prize of the Latvian SSR.

After the death of Dr. V.Veldre in 1967, R.Peterkop headed the Laboratory for one year, before R.Damburg was appointed to the position.

The works of R.Peterkop and M.Gailitis on the Wannier law and papers of M.Gailitis on asympthotic expansions of wave functions are well known and frequently quoted.

A.Gailitis, whose main field is magnetohydrodynamics, earned his Dr. degree from the Physics Institute of the Academie of Sciences of the USSR (FIAN, Moscow) in 1968, and is well known in the West by the so-called “Gailitis Dynamo.”

There were also other long-standing staff members of the Laboratory. One of them, Dr I.Vinkalns (1931-1998), has joint publications with M.Gailitis; another, Dr. R.Propin (1929-1991), has written many papers with R.Damburg. Dr. I.Fabrikant, who came to the Laboratory in 1970’s, moved to the USA in late 80-ies. From founding the Laboratory until 1994, seventeen employees had worked there. Twelve members of the LTP earned degrees of Candidate of Sciences. (The USSR Candidate degree corresponds to the PhD degree in Western countries).

Prof. L.Spruch from the New York University was the first Western scientist who visited the LTP in 1960-ies. He was followed by U.Fano and Editor of the journal Phys. Rev. A B.Bederson (both from USA), Editor of J. Phys. B M.Seaton (UK), K.Smith (U.K.), Fellow of the Royal Society Prof. P.G.Burke (UK), P.Agostini (Saclay, France) and many others.

At the beginning of 1970-ies Dr. I.Bersons and Dr. E.Karule-Gailite started to work on interaction of electromagnetic waves with atoms. E.Karule was an invited speaker at the first international conference on “Multiphoton Processes”(1977 Rochester, USA). In 1986 I.Bersons was invited to the “Multiphoton Processes” conference in Boulder, USA, and E.Karule – to the XV International Conference on Physics of Electronic and Atomic Collisions” (ICPEAC XV) in Brighton, England. Numerous invitations to make plenary reports at international conferences abroad were repeatedly received by R.Peterkop, M.Gailitis, and A.Gailitis, yet all the applications to visit Western countries sunk somewhere without any notice, maybe in KGB, the State Security Committee of the USSR.

In 1975 the LAS Publishing House in Riga published R. Peterkop’s monograph, which soon (in 1977) was translated in English and published in the USA: “Theory of Ionization of Atoms by Electron Impact”(Colorado University Press). R.Peterkop died in 1991, before Latvia had regained its independence.

In 1978 our laboratory together with the Laboratory of Spectroscopy Problems of the University of Latvia organized the International Conference on Atomic Physics (ICAP VI) in Riga. R. Damburg chaired the Local Organizing Committee. The LTP organized and hosted many seminars on atomic physics in the USSR.

In 1992 both the laboratories called the 4th European Conference on Atomic and Molecular Physics (ECAMP IV) in Riga. It was the only international conference in the Eastern Europe in the transition period for Latvia towards the independence, and some Western scientists were afraid to come to Latvia at this time. Nevertheless, it attracted about 200 foreign participants. The Local

9

Organizing Committee was chaired by E.Karule-Gailite. In 1992 she was elected to be the Head of the LTP. In 1992-1993 I.Bersons was Director of the Institute of Physics of LAS.

As a result of reorganization of science in Latvia that started in 1993, the Laboratory moved from the Academy of Sciences to the University forming the new institute in 1994.

3. 1. Laboratory of Optical Polarisation of Molecules

Main subjects of research: Experimental research of the structure and dynamics of atoms and diatomic molecules by polarised laser induced-fluorescence studies in external fields.

Research targets: IA group (alkali) dimers (Na2, K2, NaK, NaRb, NaCs, RbCs), VIA group dimers (Te2), and alkali metal atoms (Cs).

Methods: Analysis of laser-induced fluorescence (LIF): spectral measurements, relative intensity distributions in the spectra, measurements of LIF kinetic after pulsed excitation, polarisation studies, changes of LIF polarisation and circularity in external magnetic field (Hanle effect), and electric field (Stark-Hanle effect), 1 state mixing in external electric field, optical - radio-frequency double resonance, Stark effect in highly excited alkali atoms.

Experimental equipment: Argon ion lasers Spectra Physics - 2040E and Spectra Physics-171, single mode ring dye laser Coherent CR-699-21, tunable diode lasers, high accuracy wavemeter WS/6 (High Finesse), high sensitivity CCD camera (Apogee Instruments), double grating monochromators, light detecting systems in quantum counting regime, time-amplitude convertors, electromagnet up to 1 T, etc.

Some of the obtained results: Electric dipole moments: experiment and theory. Electric dipole moments in the D1 and B1 states of NaK [4] and NaRb [6] molecules have been determined; high values (7D) of the dipole moment confirm theoretical predictions.Transition moments and lifetimes: Spontaneous lifetimes of the NaK (D1), NaRb (D1 [10] and C1+ excited electronic states have been measured. Determined lifetime values confirm transition moment calculations.Non-adiabatic effects: “lambda-doubling”, spin-orbit interactions, magnetic predissociation etc. Highly accurate lambda-doubling constants in NaK [4] and NaRb [8] D1 and B1 states have been measured by RF- ODR method. Spin-orbit interaction deperturbation was applied to study NaK d3D1 and d3c3+ B1 complexes. The magnetic predissociation mechanism in Te2

has been determined [2]. Potential energy curves (PECs): The very accurate PECs of the ground state of NaRb [9] and NaCs molecules over a wide ranges of internuclear distances (up to dissociation limit) have been determined in collaboration with Hanover University by Fourier transform spectrometry.The role of the magnetic and electric fields on molecular polarization properties (alignment conversion to circularity, new approaches for dipole moment studies and electric field “imaging”): Alignment conversion to circularity phenomenon has been studied experimentally and described theoretically in NaK [5] and Te2 [2] molecules. A new original method for the electric field optical imaging based on electric field induced changes in polarization is developed [7].

3.2. Laboratory of Atomic and Molecular Physics

We have always been amazed by the difference between the world as seen daily around us and those ‘peculiarities’ that we contemplate in the quantum world. The research of quantum interference and coherent effects is one of the themes that we focus upon in the Laboratory of Atomic and Molecular Physics. It enhances in-depth understanding of the fundamental laws of quantum physics. In the research of the interference phenomenon, thanks to the large value of angular momentum of molecules, it is possible to trace in detail how the laws of quantum physics gradually transform into the laws of classic physics when we increase the angular momentum of particle. At the same time, the research of coherent phenomena in atoms and molecules is a very particular research of physical processes including the ones that in the future may have practical application for example, for designing of high sensitivity magnetometers, operating at the threshold of sensitivity, according to the laws of the quantum physics, or high sensitivity detectors indicating the presence of polluting gasses in the environment.

The subject matter of our research has helped us to find numerous interested co-operation partners both in Europe and worldwide. It has also enabled us to engage in many international research programmes.

Over the last decade the Laboratory of Atomic and Molecular Physics jointly with its partners in other research institutions has worked in the following directions and achieved the following main results:

We have studied the new mechanisms and physical effects that are capable to break the symmetry of angular momentum spatial distribution and transform initially angular momentum aligned ensemble of particles into oriented ensemble [3].

We have studied theoretically as well as experimentally the mechanisms that lead to formation of bright and dark resonances when laser radiation interacts with alkali metal vapour [5].

We have studied alkali metal vapour, placed into optical cells of sub-micron thickness. These cells allow to register sum-Doppler spectra in a relatively simple way and to study magnetic field induced circular dichroism in alkali vapour, as well as to develop magnetometers based on coherent effects in gases [8,10].

We are participating in electric permanent dipole studies in Oklahoma University and in Brookhaven National Laboratory [9].

We have described and studied in-depth associative ionisation processes that take place in collisions between excited atoms and molecules [1], we have studied also dissociative charge transfer at collisions [7] and dynamics of atomic-molecular collisions [2] and processes of photodissociation [6].

We have measured effective cross section of energy transfer and determined lifetimes for a number of excited states in atoms [4].

3.3. Laboratory of Theoretical Physics

In 1994 the Laboratory of Theoretical Physics of the Institute of Physics of the Latvian Academy of Sciences was moved to the University of Latvia. Together with the Laboratory of Spectroscopy of the University of Latvia, it started the Institute of Atomic Physics and Spectroscopy.Staff: Dr. habil. E. Gailite-Karule (Head of the Laboratory), Dr. habil. I. Bersons, Dr. A. Gailitis.Ph.D. students: R. Veilande, N. Zorina (supervisor I.Bersons). In 2001 A.Kulsh, a postgraduate student (supervised by I. Bersons) was awarded degree of Dr. Phys.

Field of research: Atoms in strong laser fields. The interaction of laser field with atoms is investigated by quantum mechanical and semi classical methods. The research is directed to obtain new approaches describing multiphoton processes. Dr. E.Gailite-Karule and Dr. A.Gailitis are engaged in the investigation of multiphoton ionization, above threshold ionization, and the high harmonic generation by perturbation theory and Floquet method. Ionization of the Rydberg atoms by half-cycle pulses is the main field of interest of Dr. I.Bersons. The applicability regions for semi classical and quantum mechanical methods are going to be determined. The research of multiphoton processes is important for plasma physics and has application in astronomy.

Main results of recent research:E.Gailite-Karule has derived the closed form of the second-order energy shift for the discrete spectrum of atomic hydrogen, which allows evaluating the level shifts in the case when the intermediate states have negative as well as positive energies. The values of the energy shift for the 1s state calculated by E.Gailite-Karule and A.Gailitis, by analytical expression obtained for the second-order perturbation theory and the more complicated and time-consuming non-perturbative Floquet approach are in good agreement up to the radiation intensity of 1013W/cm2. Results of calculations show that, except for regions close to the resonances, the rather accurate values for the energy shift of the ground state may be obtained within the second order perturbation theory.I.Bersons has developed the theory of interaction of Rydberg atoms with half-cycle pulses, which well describes the experimental results in the case of one weak impulse (P.Bucksbaum, Michigan, USA) as well as in the case of two weak impulses, shifted in time (exp. A.Wetzels, Amsterdam, Netherlands). In the case of strong pulses 1D calculations are performed. The results agree well with experimental results of J.Burgdorfer (Oak Ridge, USA).

Participation in the international activities:

1994-1999 E.Karule-Gailite was a member of the Theoretical Physics Council of the Nordic and Baltic Countries (at NORDITA, Denmark). In 1999 funding for basic research was drastically reduced and the Council was dismissed.

1992-1994 E.Karule was the member of the International Organizing Committee of the 18th and 19th ICPEAC (International Conferences on the Physics of Electronic and Atomic Collisions).

In 2000 I.Bersons was a member of the International Organizing Committee of the Super-Intense Laser-Atom Physics (SILAP) conference.

2001-2003 I. Bersons was the President of the Latvian Physics Society (LPS) and together with E.Gailite-Karule collected materials about physics in Latvia. These materials Prof. I.Martinson (Sweden) presented at the IUPAP 23rd General Assembly (GA), which was held in Brasil. In 2002 LPS was accepted to be a member of IUPAP. It was the sign of official international recognition of the achievements of the Latvian physicists.

18

In 2002 E.Gailite-Karule was elected by IUPAP GA to be a member of IUPAP GA Commission: “Physics for Development”.

In 2002 E.Gailite-Karule supervised the training course of MSc. student B.Moine from the XI University of Paris (France).

Participation in the international projects: 1993-1995 E.Karule had a joint ISF Soros’s and the Latvian Government grant. 1994 -1996 E.Karule-Gailite was a Nod (Laboratory of Theoretical Physics) leader from

Latvia in the EC 5th Framework Programme Network "Electron and Photon Interaction with Atoms, Ions and Molecules" (Coordinator: Fellow of the Royal Society P.G.Burke, UK, EC HC Network Contract ERB CHRX CT920013).

3.4. Bio-Optics and Fibre Optics Group

Head – Prof. Jānis Spīgulis

Renārs Erts, research assistantUldis Rubīns, research assistantKārlis Priedītis, engineer Inga Šīrante, project administrator

The group was founded in 1986 within the former LU Problem Laboratory of Spectroscopy with the purpose to start Latvian market-oriented research in fibre optics and optoelectronics. The first research contractors were the optical fibre manufacturing facility of Līvāni glass-works (now “Anda Optec, Ltd.”), VEF ZPI, r/a “Komutators” and others. In the 90-ies, along with the changes in Latvian science, the research was continued within the frame of LSC grants, in Ministry of Science and Education market-demanded research and integration projects, as well as within various international projects.

In 1994, when IAPS was founded, designs and model devices for optical fibre sensors and medical laser light-guide instruments were created, and mass-produced later by “Anda Optec, Ltd”. In 1995-96 entirely new linear light sources – side-emitting optical fibres and cables (patents LV 11644 B and LV 12008) were created and experimentally studied.

In 1995, J. Spigulis spent six months studying bio-medical optics at the King’s College, London, with a scholarship of the London Royal Society. Starting from the autumn 1995, he introduced a graduate sub-programme on Biomedical Optics at the University of Latvia. To strengthen the research base for the new trend, parallel research on the application of optical methods in medicine was developed, particularly on non-invasive diagnostics and monitoring. In 1998 an original device was designed and first results were obtained in diagnostics of cardiac functions and blood circulation by means of photoplethysmography. In co-operation with colleagues from Riga Stradins’ hospital (Dr. I. Kukulis, Dr. D. Klincare) and Linkoping University (Prof. A. Oberg, Prof. K. Wardell etc.) the research is successfully continued. Laser applications in oncology were studied for several years in co-operation with the Lund University (Prof. S. Svanberg, Prof. S. Andersson-Engels, Dr. K. Svanberg) and the Latvian Oncology Centre (Dr. A. Deryabo, Dr. J. Kapostins). There is a fruitful ongoing cooperation with the University of Columbia, USA (Prof. A. Hielscher), the Vilnius University, Lithuania (Prof. R. Rotomsky), Munich University of Applied Sciences, Germany (Prof. J. Schoerners), Moscow State University Pushchino Branch, Russia (Dr. N. Bystrova) and other foreign partners. In 2003 A. Grinberga from the Waterloo University in Canada worked in the Group as a guest researcher.

The research results are regularly reported at the world’s major biomedical optics symposia in San Jose and Munich, as well as at other international conferences and seminars. Over the IAPS decade the results of the Group have been presented in 52 reports and in approximately 40 papers in the international scientific journals and proceedings.

The results and experience gained in the Group’s work were used in designing of several courses at the University of Latvia (Laser Physics, Fundamentals of Biomedical Optics, Medical Light-guides, Earth Physics); currently the Group is providing two cycles of FPM student laboratory experiments – in Laser Physics (6 experiments) and Biomedical Optics (5 experiments). Over the decade the contribution to the study process at the UL includes approximately 30 bachelor and master theses accomplished in the Group. Currently two doctoral theses in medical physics (R. Erts un U. Rubins) are being prepared.

3.5. Laboratory of High-Resolution Spectroscopy and Light Source Technology

Laboratory commenced its research work in 1973 as part of the Problem Laboratory of Spectroscopy headed by Professor Elsa Kraulinya. Researchers S. Putnina (Liepa), A.Skudra, D. Bērziņa, A. Lezdinsh were later joined by G. Revalde. In 1994 when the Institute of Atomic Physics and Spectroscopy was established, the group continued its research. Presently, under the guidance of Dr. A. Skudra researchers: Dr. G. Revalde, MSc. J. Silinsh, Dr. habil. I. Bersons, as well as master course students: Z. Gavare, N. Zorina, M. Berzinsh, E. Bogans work in the Laboratory.

Low-temperature plasma and high-resolution spectroscopy have always been the main focal points of research in the Laboratory. The first research work was devoted to the excitation energy transfer between atoms in collisions of the second kind. The first research object was the mixture of mercury and thallium vapour. Later the scope of research became wider. Great efforts were put in research of low-temperature inductive coupled helium discharge plasma and helium light sources. Interesting results were achieved in research of maximum discharge efficiency of the mercury-argon plasma. The plasma of this type is very interesting not only as a subject of investigation of fundamental processes but also for its vast application including light sources and lighting. Excitation and ionisation processes are studied with regard to high-frequency discharge parameters.

Various methods of high-resolution emission and absorption spectroscopy are used in the research. A special method has been developed for investigation of emission line profiles. The method includes spectral line shape registration with a scanning Fabry-Perrot interferometer as well as the programme packet for the line shape processing and modelling with purpose to determine important quantitative characteristics of plasma.

Since 1980, in addition to purely scientific research, the Laboratory is engaged in development and manufacturing of high frequency electrodeless light sources. Initially the lamps were made for research as excellent sources of low-temperature plasma. Gradually, by using the results of low-temperature plasma investigations, the lamps were designed and improved for various applications in research equipment, e.g. atomic absorption spectrometers, magnetometers, frequency standards, spectrometers for goniometry, as well as optical pumping devices. Currently, the technology developed and 13 USSR licences registered allow to make lamps containing both pure elements and combinations of elements: He, Hg, H2, Rb, Zn, As, Pb, Sn, Te, Se, Tl, Hg+Cd, Hg+Zn, Hg+Zn+Cd, etc. Unfortunately, at present the patenting has stopped due to high prices of the European patents and the lack of funds. Nevertheless, the technologies continue to develop.

Particular attention is paid to manufacturing and research of high-quality light sources containing separate pure isotopes of a particular element, and improving them for the use in high precision quantum magnetometers and Hg analysers. Together with 5 foreign groups from France and Russia, the Laboratory of High-Resolution Spectroscopy and Light Source Technology is involved in an international project (INTAS 01-0200), for development of a high-sensitivity Hg analyser applicable for measuring of mercury concentration in air (even in the human breath due to tooth fillings), in water, and in biological specimens.

In recent years, the electrodeless discharge plasma is of interest due to possible use of the discharge as a light source (for lighting). The first models of electrodeless lamps are already on sale. However, in this area there are still some problems. Therefore, the Laboratory participates in the international cooperation programmme “Efficient lighting for the 21st century”, under which researcher Dr. G.Revalde heads a work group “New-type light sources: Electrodeless lamps”.

Recently the Laboratory has started research of application of low-temperature non-stationary plasma for use in surface processing. The plasma of this type is studied by various new methods including tuneable infrared diode laser absorption spectrometry. The research is carried out jointly with the Non-Thermal Plasma Physics Institute in Greifswald, Germany, under a cooperation agreement the coordinator of which from the Latvian side is Dr. A. Skudra.

22

Another interesting area of research is the spectroscopy of ion plasma (confined in different ion traps) by means of both, the Doppler-free double resonance and the electron cyclotron resonance methods. As a result, the hyperfine structure is measured with high precision and important physical constants, such as electronic and nuclear g-factors, hyperfine splitting constants, and hyperfine anomaly, are obtained. The research is made together with Prof. G.Werth’s laboratory at the University of Mainz. The cooperation started in 1993 when G.Revalde worked there for her doctor’s thesis.

For support of the research, the sponsors are sought because the Latvian state budget allocation can cover only salaries of a small number of scientists and part-time student-researchers which is below the subsistence level and not nearly enough to upgrade the research basis. It is admirable indeed that with funds so small internationally recognised results can be achieved.

The outputs of the Laboratory are regularly published and demonstrated in conferences and exhibitions. The Latvian Council of Science deserves gratitude for its assistance in covering of conference participation fees otherwise even such participation, which is important for reporting of the research results, promotion of the Latvian science, and establishment of contacts, would not be possible.

In addition to scientific research, the staff of the laboratory sometimes, without any remuneration, provide lectures to the students of the Faculty of Physics and Mathematics, UL and supervise the master’s and bachelor’s theses. Courses of lectures are: “The atoms and ion cooling, trapping and spectroscopy” (G.Revalde, 3rd course, for physics bachelors), “Patents” (A.Skudra, for physics masters), “Non-coherent light sources” (A.Skudra, for physics masters).

3.7. The Group of Atomic and Atmospheric Physics and Photochemistry

At the 10th anniversary of the Institute, the Group of atomic and atmospheric physics and photochemistry represented the following experienced and enthusiastic team:

Head of the group Dr. phys. Arnolds Ubelis Students working in the team:Dr. habil. phys. Uldis Berzinsh Edgars Šmaliņš, postgraduate studentDr. phys. Jānis Āboliņš Jānis Puķīte, postgraduate studentDr. phys. Uldis Gross Jurģis Kalvāns, graduate studentMSc. Dina Bērziņa Māris Kuņickis, graduate studentMSc. Juris Silinsh Agris Kalniņš, graduate studentProf. Jānis Grāvītis, cooperation in projects Māris Siliņš graduate studentDr. phys. Māris Ābele, cooperation in projects Liene Āboliņa graduate studentMSc. Jānis Vjaters, cooperation in projects

The anniversary publication obliges to look at the activities of the Group in a historic perspective – provide answers to the questions about the choice of research direction, argumentation, and future prospects.

In 1964, J.V.Kasper and George C. Pimentel published a paper on iodine photo-dissociation laser with emission at 1.315 μm, obtaining inverted population in the metastable state 52P1/2 of the atomic iodine at photo-dissociation of CF3J and CH3J. (See: J.V.Kasper, G.Pimentel, Iodine Photo-dissociation Laser (CF3J, CH3J) - Applied Phys. Lett. 5 (11) 1964, pp. 231-233) Shortly afterwards, in 1968, the author of the current review, the 5 th year student at the time, had a conversation with the Associated Professor Elsa Kraulinya at the Faculty of Physics and Mathematics of the University of Latvia, about joining to the research project proposed by the State Institute of Optics in former Leningrad (now – St. Petersburg): “Selenium and tellurium atoms in the metastable states and their reaction constants“. Decidedly, that tempting offer was accepted. Both the elements in the gaseous phase (vapour) are in the molecular state, and it is problematic to perform experiments with atoms. It turned out that the most appropriate technique for this purpose was photolysis (See: G.Porter. Flash Photolysis and Some of Its Applications, Nobel Prize Lecture, Science 160 (3834), 1954, pp.1750-1767.

After the offer of participation in the research project was accepted, a congruent group of experimenters was formed – the author of the current review, Juris Silinsh and Janis Rupkus. High-temperature flash photolysis equipment was built. Initially the interest was focused on metastable Se and Te atoms. Afterwards, the experiments with Pb, Sn, Cu, and Tl atoms, in the metastable state, were also carried out when photolysis of bromides and iodides of these hard-to melt elements was performed in the vapour phase. On the whole, these activities became incorporated within the field of chemical physics. The union of atomic physics and photochemistry brought practical results that were useful to people involved in the development of laser technologies. In 1988 Uldis Gross built an excimer laser.

The obtained experience arose the interest in sulphur and oxygen - elements of the oxygen subgroup. A stimulus for this was the world convention in 1985 about protection of the ozone shield. It was obvious that the group had a certain capacity to participate in research projects related to atmospheric problems. The changes that occurred in Latvia around 1990, opened the “iron curtain” that separated Latvia from the Western world, and as early as in 1990 Uldis Berzinsh of our group travelled to Gothenburg and Lund, to participate in atomic and ion laser spectroscopy experiments, in cooperation with Swedish professors M. Gustaffson and S. Svanberg. The current idea was to study lifetimes of various atoms in excited states. The objects of studies were atoms of selenium and tellurium as well as sulphur, arsenic, phosphorous and others. The most exotic objects were negative ions.

27

In 1993 contacts were established with professor J. Burrows at the University of Bremen, and Uldis Gross became involved in the experiments of flash photolysis of iodine-ozone. Results of these experiments are important to people working with problems of degradation of stratospheric ozone. Our contribution was significant experience in experiments of photolysis and special spectral sources of atomic iodine. It allows to detect and to control the concentration of iodine atoms in the iodine-ozone mixture. It is interesting to note, that the results of this work were referred to by Paul Crutzen, who received the Nobel prize in 1995 for his work in the chemistry of ozone layer and photochemistry. The interest of our group in questions posed by research of atmosphere increased, and in 1996 we were invited to participate in the EUROTRAC-2 project within the EUREKA programme about the transfer of atmospheric pollution over Europe and chemical changes in the polluted atmosphere. This project was finished in 2002, providing a basis for a EU 6th Framework programme project No.505337 (2004-2008): ACCENT – Atmospheric Composition Change – Network of Excellence. The project proposal was supported notwithstanding the great competition of applications within the calls of the 6th Framework programme, and our group (and, consequently, the Institute and the University of Latvia) is a partner of the current project’s consortium. It makes us members of an excellent club of atmospheric researchers in Europe. This achievement adds confidence in the competence and future prospects of our group.

The greatest benefit is granted to our students, who now have clear prospects of scientific interest and career in a very substantial field of scientific research. Hopefully Edgars Šmaliņš and Jānis Puķīte will be the first ones to benefit from the new opportunities. This project is also a basis for uniting our efforts with other colleagues within the UL. The first step is cooperation with Jānis Vjaters and Māris Ābele at the Institute of Astronomy. Their scientific experience is being used in an application of Erth satellite sensors to atmospheric research, i.e. the project of so-called “white light beam”.

The atmospheric research issues are a part of knowledge transfer to graduate studies “Physics and technologies for sustainable development”. Here our group, including Jānis Āboliņš and Dina Bērziņa, develops cooperation with Professor Jānis Grāvītis from the Institute of Wood Chemistry and implements other activities.

A deeper insight into the activities of the group can be gained from the list of publications attached to the current review. Details can be found in the home page of the Institute (http://home.lanet.lv/~asi/en/groups.htm).

In the conclusion it is important to note that overall success of the Group’s work from the very establishment of the Institute is a result of unselfish attitude. If the state support to science in Latvia had not been the most modest among all the new EU member states, the scientific potential, as well as achievements of our Institute and the Group would have materialise in a more serious competitive capacity of the country. We are working in the field, where fundamental science goes hand in hand with practical needs of public and private sectors and where a demand for highly qualified scientists and experts with a good experimental basis is increasing rapidly. With appreciation of our efforts and support from the National Government we could attract great commission projects and participate in significant EU-level projects with a much more extensive funding than is available from the national budget. It means investment in work places and university infrastructure, which would grant continuous high quality studies and research training for students.

7. Activities of the Examination Board and awarded degrees, 1994 -2003

For ten years since1994, the Institute of Atomic Physics and Spectroscopy at the Faculty of Physics and Mathematics (FPM) is housing one of Examination Boards of the University of Latvia – the Board for physics. It was a board with a right to confer habilitate titles and doctoral degrees (i.e., habilitation and promotion). As in 2000 the two-stage system of scientific degrees (Dr. habil. and Dr.) in Republic of Latvia was abolished, it became the Promotion Board.

Until 1994 two disciplines – astronomy and optics - were represented at the Board. By the initiative of Prof. Maris Jansons, Chairman of the Board, and Prof. Ruvin Ferber, Deputy Chairman, the competence of the Board was expanded to include theoretical physics and spectroscopy along with optics in 1994, the year IAPS was founded. The number of the Board members was expanded to 10 experts and included habilitated doctors: I. Bersons, R. Damburg, R. Ferber, E. Gailite, M. Jansons (IAPS), B. Rolovs, I. Vitols (FPM), J. Zaķis (UL), J. Francmanis (Radio-observatory of LAS) and V. Straizys (Institute of Theoretical Physics and Astronomy, Vilnius, Lithuania).

In the following period, from 1997 until 2000, it was necessary to merge spectroscopy and laser physics, and to separate optics as an independent sphere, and to include didactics of physics. As a result, the five sub-disciplines were approved to belong to the competence of the Board. The expert group of the Board was complemented with Professor I. Lacis and two young habilitated doctors M. Auzinsh (1995) and M. Tamanis (1996). Didactics of physics mainly represented by experts from the FPM staff. Prof. I. Lacis, whose speciality is optometry, was responsible for optics, while responsibilities of M. Auzinsh and M. Tamanis involved optics, as well as laser physics and spectroscopy.

Head of the Board Prof. Maris Jansons passed in 1997. Soon afterwards, Professor Juris Francmanis died in 1998. The Deputy Head of the Board - Prof. R. Ferber - was elected to the Chairman. The post of Deputy Chairman was assigned to M. Auzinsh. Both professors still retain their posts at the moment. O.Lielausis (Institute of Physics of the LAS) was invited to be expert in astronomy. A recommendation of the late J.Francmanis was implemented - astronomy became the second discipline, with astrophysics and fundamental astronomy as sub-disciplines. Thus more precise description of the expert competence, and direction of astronomy developing in Baltic States were given. For some time didactics of physics was still retained. Initially the responsible expert in didactics was only M.Auzinsh, later joined by E. Shilters who became Dr. habil. phys. in 1998. Under “strategic” scientific considerations optometry was included as a sub-discipline; the experts were Prof. I. Lacis and Prof. I. Vitols, both greatly contributing to the rapid development of this discipline at the University and in Latvia.

A new period began in 2000, when the Cabinet of Ministers of the LR issued a decree, regulating procedure of promotion– i.e., awarding only the Dr. degrees. Appointing of experts became a competency of the Latvian Council of Sciences (LCS). The number of mandatory publications to qualify for a post of expert was closely monitored, and new experts appointed. As a result, the constitution and competence of the Board were changed. The sub-discipline of optometry is no longer represented, however, passing away of Prof. I. Vitols (2000) could not be the only reason. V. Straizys retired from his post as an expert of the Board due to other engagements. R. Damburg became an Emeritus Scientist and did not apply for the post.

The work of the Board in the period from 1994 until 2003 has contributed to the increase of the number of experts in physics. In IAPS, Dr. degrees were awarded to12 scientists, including 3 Dr. habil. Three nostrifications (in March of 1994) were followed by the Decision of the Board No. 60 on awarding Marcis Auzinsh a Dr. habil. phys. degree (1995). No. 85 in the list of applicants stands for award of Dr. phys. degree Vilnis Frišfelds (2003). Consequently, the UL Board in close relationship with the IAPS members, has awarded degrees of physics doctors to 26 individuals. 12 among them are from the Institute (pp. 91-92).
