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 kelvin

Name: B-10 Lib80x
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.
