Accurate nuclear data are needed for the development of clean nuclear power systems that employ accelerator-driven technologies. To meet this need for thorium - based on the experimental data of total, nonelastic-scattering, fission, and other reaction cross sections and elastic-scattering angular distributions of 232Th - all cross sections of the neutron-induced reaction, angular distributions, energy spectra, gamma-ray production cross sections, gamma-ray production energy spectra, and number of neutrons per fission are calculated and analyzed for n + 232Th at incident neutron energies from 0.05 to 20 MeV. The analysis includes the double-differential cross section for neutron, proton, deuteron, triton, and alpha emission. Theoretical calculations are compared with existing experimental data and other evaluated data from ENDF/B6 and JENDL-3.
