Calculations and Evaluations of Neutron-Induced Reactions on ^180m,181Ta

The neutron reaction data of ¹⁸¹Ta for the incident energy up to 200 MeV are urgently required for the study of nuclear reactor systems of fission or fusion. To meet this requirement, all cross sections, angular distributions, energy spectra, and double-differential cross sections for n + ^180m,181Ta reactions are consistently calculated and analyzed at incident neutron energies up to 200 MeV. The theoretical results are compared with the experimental data and the evaluated results in ENDF/B-VIII, JENDL-4, and JEFF-3.
