Abstract: The experimental results available through September 1978 from the various reaction and decay studies leading to nuclides in the A = 159 mass chain have been reviewed. These data are summarized and presented, together with the adopted level schemes and properties.

Acknowledgments: The authors thank R. C. Greenwood, D. G. Burke, and P. E. Haustein for sending their data prior to publication. The authors also thank C. M. Lederer for communi- cating information froln the Table o f Isotopes on the A = 159 mass chain. Special thanks are due R. L. Bunting for many helpful discussions and W. B. Ewbank and the staff of the Nuclear Data Project for assistance with computer programs and for a critical review of the manuscript.

GENERAL ORGANIZATION OF MATERIAL

Within each A-chain, information is collected by isotope and arranged in order of increasing Z. For each isotope, AZ, the arrangement of material and conventions for inclusion in tables are described below. Uncertainties are shown whenever available.

I. Adopted levels in AZ - All adopted level properties are shown for each level, together with explanatory comments.

2. Radiations from AZ decay - All adopted radiation properties are shown for each a - or 3,-radiation from decay of the AZ ground state. Properties of e - , /3 + - or /3--branches are shown if they have special interest.

3. Radiations from AZ isomeric-state decay - Decay of each isomeric state is presented according to the same conventions as for the ground-state decay.

4. Levels in AZ "1 (Reactions are ordered by A, Z of target, then deduced from decay t by A, Z of incident nucleus.) A heading is

5. Levels in AZ given for each reaction. The detailed results deduced from nuclear reaction are tabulated only when the information is

6. Nuclear-reaction "t-rays not adequately summarized on the drawings.

*Work performed under the auspices of the US Department of Energy

Decay scheme: The absolute ~ feeding to levels in tsPGd is unknown. The

endpoint of the highest energy 8 branch, 2570 key 50, has been measured by 65Iw01, who assume that this branch feeds the ground state of *sPGd. ~ study of the 7-ray transitions following the tsPEu decay was carried out by 69Kei0, who assume that this ~ branch feeds the 67.8-key level and that there is no ~ feeding to the ground state and the 50.7-key first-excited state. Depending on what assumptions are made concerning the distribution cf ~ intensities among the lowest four levels in *SPGd, the intensity of the 2570~ may range from 20~ to 35~. Consequently, no assumptions are made here regarding the ~-branching intensities.

The decay scheme is due primarily to 69Kei0; however, in view of the uncertainties in the 8 branching intensities the I(~)- and log ft-values of 69Ke10 have been omitted. the energy levels in *SPGd populated in *SPEu decay agree well with reaction studies.

Measured ~ energies include: 1000 key 100 87-coincidence (65Iw01). 1500 key 50 ~7-coincidence (65Iw01). 1750 keV 50 87-c oincidence (651wO I). 1850 key 50 scin, F-K (65Iw01}. 2200 keV 100 scin, FoK (61Ku10). 2350 key 50 scin, F-K (651w01). 2570 key 50 scin, F-K (65Iw01). 2400 key ~20-I0 scin (66Da06).

The decay scheme is due primarily to 698r05. The level energies have been adjusted by the evaluators. The @-branching intensities and the 7-ray normalization

have been calculated from the listed 7-ray intensities by requiring intensity balance at each level, using the g.s. 8 branching intensity of 62~ 9 from 758aXG.

T,/2: microwave (70Ar22).

Jr: 5/2(413) Nilsson state.

Jw: 5/2(532) Nilsson state. The 5/2(532) and 7/2(523) Nilsson states originate from

the hii/2 shell-model state and are expected to have strong Coriolis coupling.

mE: estimated by evaluators. Jr: 7/2(523) Ni!sson state. Some admixture of the 7/2

member of the 5/2(532) band is expected due to Coriolis coupling.

&E: estimated by evaluators. T,/a: resonance fluorescence (66Ra06). J~: 71Bu16 indicate that this band is primarily a 7

vibration based on the 3/2(411) g.s. with possibly some admixture of the 1/2(411) Ni!sson state.

from 72Bo47 and 72Ti05. Jr: 71Bu16 suggested the 1/2(541) Nilsson assignment for

this level. The results of 72Bo47, 72Ti05 and 69Br05 are consistent with this choice but are not sufficiently conclusive to make a definite assignment.

&E: estimated by eva!uators.

Jw: assignment is consistent with results of stripping reactions (72Eo47, 72Ti05). Possibly a member of the 1/2(541) band.

Jr: 72Ti05 assign an unresolved doublet observed at 945 keV in (~,t) and at 949 keV in (aHe,d) as the I/2(411} Nilsson state and the 3/2- member of the 1/2(541) band.

7(*SgDy) from *sgDy IT decay (122 ps) 68Bo18, 67Co26

Isomer produced by *S"Tb(d,2n) reaction (68Bo18) with Ed=12 ~eV, and by *SgTb(p,n} reaction (67Co26) with Ep=5, 8, and 17.5 MeV.

The decay scheme given here is due to 68Bo18. Conversion electron intensities for transitions

of E<137 key have been renormalized by the evaluators using ~(L)=2.08 for the 99.6-key transition.

IT-normalization: calculated by evaluators, requiring total transition intensity depopulating the isomeric state to equal 100%.

E(level): authors disagree with 73K113, who assign the 523.47 as the 27/2+ to 23/2+ transition, thereby placing the 27/2+ level at 1797.8 keY. On the basis of tentative 7-ray transition placements, 718o38 place the 27/2+ level at 1795.8 keY.

E(level): based on observed transition with E7=580.9 key and energy of 1775.0 key for the 27/2+ level. See comment on 1775.0-keV level.

E(level): based on observed transition with ET=6q7.~ key and level energy of 2355.9 key for the 31/2+ level. See comment on 1775.0-keV level.

E(level): the 769.77 has been tentatively placed by 74DaZH as the 49/2+ to 45/2+ transition, leading to a level energy of 5096.0 keVo However, the transition was too weak for angular distribution measurements.

other measurements: 75GaYZ The decay scheme is due primarily to 71Bo18. For conversion-electron data the reader may refer to

71Bo18, 68Ab15 and 73Tu05. IT-normalization: based on assumption of no • branch to the

• SSDy ground state and requiring intensity balance at each level. Theoretical conversion coefficients for the multipolarities given by 71Bo18 were used in determining Iv-normalization.

71Bo18 indicate that the uncertainty in the 7-ray intensities and in the conversion electron intensities is of the order of 10~, except for weak transitions where the uncertainty may be 25~. Evaluators have used AI7=25% for transitions of 17<10. Evaluators have assumed an uncertainty of 15% in L-subshell ratios to calculate A6.

Source produced by t6SHo(p,Tn) reaction followed by mass separation (77Bo267 , and by LS3Eu(ttB,5n) reaction (77HaYTT. The adopted decay scheme is essentially that of 77Ho26. 77HaYT deduced a decay scheme with 21 transitions placed among 14 excited levels up to 1445 keV. The two decay schemes are in good agreement ccncerning the more strongly fed levels in *sPHo, bgt differ in the energies of some of the more weakly fed levels and the placement of weaker T-ray transitions.

t Level energies have been adjusted by the evaluators. 77Bo26 show this level in the decay scheme, but do not show any transitions depopulating the level. The (=,t) and (3He,d) experiments of 77Pa23 indicate a level of spin 5/2- at 464 key which is assigned as a member of the I/2(5417 rotational band. However, from the data in 77Bo26 it is not clear whether the level is populated in the decay of *SgEr.

7(tsgHo) from *SeEr ~ decay 77Bo26, 77HaYT

Source produced by *6SHo(p,7n) reaction followed by mass separation (77Bo26), and by *S3Eu(**B,5n) reaction (77HaYT). The adopted decay scheme is essentially that of 77Bo26. 77HmYT deduced a decay scheme with 21 transitions placed among 14 excited leve!s up to 1445 keY. The two decay schemes are in good agreement ccncerning the more strongly fed levels in tSgHo, bet differ in the energies of some of the more weakly fed levels and the placement of weaker 7-ray transitions.

IT-normalization: calculated by evaluators, assuming zero g.s. branching and requiring intensity balance at each level.

7(*SPEr) from tSPTm E decay 75Ag03, 75St07 ......................................................

75~g03 obtained *SgTm sources from the (p,xn) reaction fcllowed by on-line isotope separation. 75St07 obtained *SPTm sources from the (p,xpyn) reaction on Ta, followed by chemical and isotope separation. The decay scheme is due primarily to 75Ag03. 75St07 have published a decay scheme containing levels up to 566 key which is in substantial agreement with that of 75A903 for levels up to 429 keY.

IT-normalization: the IT-normalization is based on the partial decay scheme, in which ~81 percent of the total observed 7-ray intensity has been placed, so 17-normalization should be regarded as uncertain.

See 75Ag03 and 75St07 for conversion-electron data.
