The ENDF62MT Multi-temperature Neutron Library contains data for 235U, 238U, and 239Pu at seven temperatures (77, 400, 500, 600, 800, 900, and 1200 K). These data use the same source evaluations as as were used for the ENDF60 library, Release 2 of each nuclide. However, a tighter fractional tolerance on thinning was used for ENDF62MT, so the data files are larger in size than the corresponding 300° data files in the ENDF60 library.
ENDF62MT can be downloaded either as a zip file or as a compressed tarball
