ENDF70 is a continuous-energy neutron data library for use with MCNP versions 4C and later (required because of the tabular angular distributions). The library contains data from 390 of the 393 ENDF/B-VII.0 evaluated nuclear data files. The data were processed using the NJOY99.248 code and include, as appropriate, data for:
The ENDF70 library, due to its 8GB size, is stored in 11 separate files (endf70[a-k]) and contains data for 5 temperatures:
The ENDF70 library is the first ACE library release based on the ENDF/B-VII library and the first major release since the ENDF66 library. It supersedes the ACTI library (based on ENDF/B-VI, Release 8), ENDF66 library (based on ENDF/B-VI, Release 6), URESA library (based on ENDF/B-VI, Release 4), and ENDF60 library (based on ENDF/B-VI, Release 2). These ENDF/B-VI based libraries have been in production use since 2002. The ENDF/B-VII library represents a major update to the ENDF/B library. It is based on a revised set of international standard cross sections, includes major updates for almost all the actinides, an entirely new set of fission product data, and updates to many of the light isotopes and structural materials.
ENDF70 can be downloaded either as a zip file or as a compressed tarball
