JAVA-NDS: B. Singh (McMaster Univ.)

• Developed started in 2007 with contract from NNDC, BNL to Roy Zywina; and my interaction with Roy. A code supplied by Roy in January 2008 was not operational; Roy quit after half-time of contract term.

• Later work by Scott Geraedts and Jeremie Choquette in 2008-2011; workable version presented at 2009, 2011-NSDD meetings.

• In 2011 or so a complete A=182 chain was prepared in NDS style.

Output reviewed by several evaluators, and Marion Blennau. • Review copy of A=75 was produced using this code and sent to

reviewer.• Sept 2011, turned over this code to NNDC for further improvement and

smooth working. • For several A-chains published in NDS, Marion Blennau used this

code to generate band drawings, until quite recently.• Marco Verpelli at IAEA-NDS is using this code for some level-scheme

drawings.

Pros:

• Similar layout as that of the NDS-PUB. No difficulty and discomfort for users in transition from old layout.

• Times New Roman used as the standard font, as in most journals• Final level and JPI added for each γ-transition, making it

convenient for user to read. In current NDS-PUB output, sometimes it is frustrating to keep turning pages between the level table and the gamma table in order to check the final level and its JPI for a gamma transition.

• Better band drawing function than NDS-PUB. Since 2009 or so, this function has been used for band drawing in NDS publication of mass-chain evaluation.

Pros:

• Easy maintenance of the program. It is well written with the modern and popular programing language JAVA, compared with the FORTRAN for the old NDS-PUB program. JAVA is more powerful and flexible in dealing with file and string input/output; is in object-oriented language, and is easy to read, understand and modify.  

• User-friendly graphical interface makes it very easy to use.• The new NDS-JAVA program can produce an output with similar

layout to the NDS-PUB, but with many advantages and improvements. The outdated NDS-PUB program needs to be replaced in the long run. Now that there is an alternative available (NDS-JAVA), people should pay more attention to it and think about its feasibility.

Jun Chen’s comments..

Cons:• No final stable version is available since no one has worked on it

since 2011-2012. It should go through many tests before it can be made available to NSDD network.

• One needs to manually change the page orientation for wide tables in a global control file. It is time-consuming. Function needs to be added in the program for selecting the orientation automatically according to table widths. Work needs to be done in creating a better and more useful “control file”.

Demo of this code for A=43 chain

• Default control file generated by the code was edited around 2012• He had also written a brief manual for using this code.
