Improved Evaluations of Neutron-Induced Reactions on Americium Isotopes

The suite of neutron-induced reactions on ²⁴¹Am, ^242gAm, ^242mAm, and ²⁴³Am has been evaluated for incident neutron energies above the unresolved resonance region and up to 20 MeV. Modern theoretical models and computational techniques were extensively used because of the rather limited experimental information. However, when available, experimental data were used to guide and benchmark the present evaluation work. All evaluation results were formatted and distributed as ENDF data files for possible inclusion in the ENDF/B-VII library.
