Fission, capture, neutron-elastic-scattering, and inelastic-scattering data for the 233U are described within a Hauser-Feshbach-Moldauer theory. The rigid rotator optical model potential is obtained based on the total cross section, elastic-, and inelastic-angular distributions. Consistent estimates of capture and fission data are obtained up to E n ∼1 MeV. Prompt-fission neutron spectra are calculated with the model that takes into account the contribution of neutrons emitted in (n,xnf) reactions. Exclusive pre-fission (n,xnf) neutron spectra are obtained by fitting of the fission cross section. Local minima of the average energies of prompt-fission neutron spectra at E n ∼7 MeV and E n ∼12 MeV are predicted. A 233U evaluated data file is produced.
