The Joint Evaluated Fission and Fusion File 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 new JEFF-3.1.1 general purpose library is in ENDF-6 format and contains incident neutron data for 381 isotopes or
elements from 1-H-1 to 100-Fm-255. The library and its performance are described in the
JEFF Report 22.
The evaluations available on this page correspond to the evaluations distributed on the JEFF3.1.1 CD except for
some format corrections. The evaluators comments and references as reported in the data files (MF1/MT451) are
available in JEFF311-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-311.txt.
