This library is based on ENDF/B-VIII.0. It contains ACE files for continuous-energy incident neutrons. These have been processed at the following temperatures (with their respective ZAID extensions).
.00c — 293.6 Kelvin (Room Temperature).01c — 600 Kelvin.02c — 900 Kelvin.03c — 1200 Kelvin.04c — 2500 Kelvin.05c — 0.1 Kelvin.06c — 250 KelvinThe full documentation for the Lib80x library can be found in the docs directory after decompressing the download.

Description: After the release of ENDF/B-VIII.0 in February 2018, errors were discovered in the neutron on B-10 evaluation. A fix was provided for the errata; this update uses the fixed B-10 evaluation. For more information on the updated/fixed evaluation, please see: https://www.nndc.bnl.gov/endf-b8.0/errata.html.
