Consistent evaluation of the 232Th capture cross section is performed in the energy range from 4 keV to 5 MeV. The Hauser-Feshbach-Moldauer theory and coupled channel optical model are employed. Total, differential scattering, fission, and inelastic scattering data are consistently reproduced as a major constraint for the capture cross-section estimate. Average resonance parameters are obtained, which are consistent with the capture cross-section database.
