Validation of a large activation cross-section library
The 63-group neutron cross-section library used for neutron activation studies in the Nuclear Theory and Applications Group at Los Alamos has a variety of sources of widely varying levels of quality. This heterogeneous aspect, which is a common feature of all libraries used in activation studies, is a direct consequence of the need to quickly obtain data for up to 15,000 different excitation functions involving 750 different targets. Because of the need to assess the reliability of this library and ten to improve it, we have initiated a systematic comparison of this library with three main data sources, especially the large CSISRS online data system, maintained by the National Nuclear Data Center at Brookhaven National Laboratory. We report on the results of extensive comparisons between the experimental data and the multigroup library. We briefly mention new theoretical approaches data evaluation that are suitable for meeting future data needs in this area.
