CAB models for water: A new evaluation of the thermal neutron scattering laws for light and heavy water in ENDF-6 format

摘要

In this work we present the CAB models for water, a set of new models for the evaluation of the thermal neutron scattering laws for light and heavy water in ENDF-6 format, using the LEAPR module of NJOY. These models are based on experimental structure data and frequency spectra computed from molecular dynamics simulations. The calculations show a significant improvement over ENDF/B-Ⅵ and ENDF/B-Ⅷ when compared with measurements of differential and integral scattering data.
