Date: 4 May 2005

The Joint Evaluated Fission and Fusion File (JEFF-3.1) is an evaluated library produced via an international collaboration of Data Bank member countries co-ordinated under the auspices of the NEA Data Bank.
The general purpose neutron library is in ENDF-6 format and contains incident neutron data for 381 materials from 1-H-1 to 100-Fm-255. The data can be obtained in a number of ways. The files can be downloaded in a tar-file:

Below follow links to the individual files with the complete library tape listed first.
The evaluations available in this page corresponds to the evaulations distributed with the JEFF3.1 CD except for some format corrections.
The evaluators comments and references as reported in the data files (ENDF format MF1, MT451) are available in JEFF31-MF1-N.html.
A summary of the data source and evaluators can be found in jeffsource-N.txt.
All available reactions (MFs and MTs) are listed in MF-table-N.TXT.
