Abstract：
Based on the spherical optical model,the Coupled-Channels theory,the empirical formula based intranuclear cascade mechanism for nucleon emission,the exciton model,the evaporation model and the Hauser-Feshbach statistical theory with width fluctuation correction, the reaction data are calculated for p+²³⁸U in the energy region from threshold up to 200MeV,the fission widths are calculated with Bohr-Wheeler formula.The calculated results are generally in good agreement with the experimental data.
