Last modifications:

2021-12 Java-NDS
Fixed a bug that causes limits in continuation records not being printed correctly
Few bug fixes, e.g., missing flagged footnotes in delayed particle tables.
2021-11 AME-viewer
A simple instruction is included in the program and can be popped out by clicking on the "?" mark on the program window.
2021-06 GABS
Bug fix:
(a) %DIG was incorrectly evaluated if BR < 1.0;
(b) using the "-M" option to find transitions feeding to the ground state, TI values are not included in the summed total intensity.
(c) %IG values were produced from the total intensities (TI), when no conversion coefficient (CC) was given.In these cases %IG=TI, instead of %IG=TI/(1+CC).

All executables are for 64 bits operating systems. The MacOs version was compiled on Big Sur version 11.4 using the 2021 Intel compiler.
2021-06 BetaShape
Version 2.2, with CSV production and executables for any platform (for Mac: both M1 and Intel)
(developed by X. Mougeot, CEA-LHNB) The code can be downloaded from the LNHB web site
All feedback should be sent directly to Xavier Mougeot
2021-04 JAVA-NDS, Java Ruler, Excel2ENSDF
Minor fix
GTOL for Windows
Correct version displayed in the output header of the code.
AME viewer
Tool for retrieving and displaying AME data entries (AME2020).

Previous modifications:

2021-03 JAVA-NDS
Bug fix: in datasets where there are bands based on different unknown levels X and Y, gamma rays from some member states in those bands could be mistakenly identified as unplaced transitions by the previous version.
ConsistencyCheck
More checking items have been included, and improved level-matching algorithm for matching levels from different datasets.
2021-02 BetaShape
Beta spectra calculations (developed by X. Mougeot, CEA-LHNB)
The BetaShape program has been extented with the treatment of EC/B+ trasitions. The code can be downloaded from the LNHB web site
All feedback should be sent directly to Xavier Mougeot
2021-02 JAVA-NDS Bug fixing
2020-11 ALPHAD, RadD, ALPHAD-RadD New Versions
2020-08 JAVA-NDS Bug fixing
2020-08 BrIcc & GABS
BrIcc: Following the 23rd NSDD meeting, held at the IAEA (8-12 April 2019) the calculated total conversion coefficient, CC will be only put on the G or on the G-continuation record (DCC is asymmetric), if the CC eld is blank and the G-continuation record does not has CC. All other cases, CC will be put on the S G record. The rounding of uncertainties has been also changed to follow a widely used protocol in a number of scientific communities.
GABS: Bug fixing
2020-04 GABS Correction of %IG uncertainties calculation for transitions used for normalisation when BR smaller than 1.0
2019-10 Consistency Check New version of the utility code replacing Pandora
2019-09 BrIccMixing minor change to solve installation issues
2019-09 GABS new version The new version of GABS presented at the last NSDD meeting in Vienna.
The new code has three operation modes:
[F] - NR and BR will be obtained from a fit (using G`s marked with "X")
[C] - Calculate TI using NR and BR from the N-record in the input file
[M] - Mark transitions going to the g.s. by "X" (DRI>0) & "Y" (DRI blank)
The syntax to use in the [F] mode is simply "gabs -f myensdf.ens".
For further information see the NSDD 2019 presentation on GABS. Please report problems and suggestion to Tibor.Kibedi@anu.edu.au
2019-09 JAVA-NDS A few errors and bugs (mostly minor) have been reported and fixed, for example, incorrect arrows for decay modes in the skeleton drawing.

2017-03 Java-nds
ENSDF publishing code
Java-nds produces Nuclear Data Sheets-like pdf file from a ENSDF input
2016-08 JGAMUT - under development
JGAMUT (written by Michael Birch, McMaster University) is a Java version of the old GAMUT code which produces an Adopted Levels, Gammas (ALG) dataset from all other input data sets. The purpose for such a code is - among others - to make producing an ALG dataset less labour-intensive for evaluators and more standardized among evaluators. Included in the zip files are the source code, executable jar file, user manual and example files. In addition, for those that work on any future development of the code, there is a "javadoc" in the "dist" folder which provides detailed information about the classes and methods defined in the source code. Instructions on how to install and use the code can be found in the manual. Questions, comments and suggestions related to these codes should be sent to Michael Birch birchmd@mcmaster.ca with CC to Balraj Singh balraj@mcmaster.ca
2016-01-28 Fmtchk (Utility tab)
Removed check for NP to be equal to BR on N card.
Suppression of many warning messages, e.g., absence of MR for mixed multipolarities, Y2K check, messages when T, L, or S are relabeled, QP is negative.
The NNDCLIB library included in the package has been modified to compile with gfortran, intel fortran, LF 95 compilers on all platforms
2015-04-02 V.AveLib (Utility tab)
Averaging Experimental Values.
2015-04-02 GABS new version
In some cases the uncertainty of the normalised gamma intensity was incorrectly reported in the output ENSDF file: '**' was given instead of a numerical value.
Warning is given if no gamma transition is marked to be used for normalisation by inserting 'X' or 'Y' in column 79.
Old comment gamma records with the calculated normalised intensities are removed/replaced with new ones.
2015-03-10 RadD program added - Deduces radius parameters

NSDFLIB
Nuclear Structure Data File Library

This library consists of subprograms used by many of the ENSDF Analysis and Utility Programs. FORTRAN 77 and FORTRAN 90/95 versions of the library exist. Both contain string processing, which extend the capabilities of ANSI standard FORTRAN, number to string and string to number, and mathematical subprograms. The FORTRAN 90/95 version also has command-line interpreter, time and date, and sorting subprograms.

FORTRAN 77 source code
FORTRAN 95 ANSI source code
FORTRAN 95 Linux make file
FORTRAN 95 Linux compressed file
FORTRAN 95 Windows source code This program, and all other NNDC distributed software, has been written in ANSI standard FORTRAN so as to be as machine independent as possible. However, there are places in the programs where nonstandard features of the FORTRAN language have to be used. As a result, some sections of the code are written in a machine dependent manner. The variant codes appropriate for particular computers have all been included in the program with the inappropriate code stored as comments. Program SETMDC will convert programs from one configuration to another so as to make machine portability as simple as possible.
