Abstract
Evaluation of neutron nuclear data for 172 nuclides from As to Tb has been made for JENDL-3. Evaluated quantities are the total, elastic and inelastic scattering, capture and threshold reaction cross sections, the angular and energy distributions of secondary neutrons in the incident neutron energy range from 10-5 eV to 20 MeV. The evaluation was made on the basis of theoretical calculations with optical, statistical, preequilibrium and multi-step evaporation models as well as available experimental data. Below 100 keV, resolved and unresolved resonance parameters were evaluated. The benchmark tests performed by comparing with experimental data at STEK, EBR-II and CFRMF have confirmed the reliability of the present evaluation.Keywordsnuclear datacross sectionsresonance parametersangular distributionsenergy distributionsevaluationfission productsbenchmark testsJENDL-3
