摘　　要：A set of optimal proton optical potential parameters for pd-lS4w reactions are obtained at incident proton energy up to 250 MeV. Based on these parameters, the reaction cross-sections, elastic scattering angular distributions, energy spectra and double differential cross sections of proton-induced reactions on lS4w are calculated and analyzed by using theoretical models which integrate the optical model, distorted Born wave approximation theory, intra- nuclear cascade model, exciton model, Hauser-Feshbach theory and evaporation model. The calculated results are compared with existing experimental data and good agreement is achieved.A set of optimal proton optical potential parameters for pd-lS4w reactions are obtained at incident proton energy up to 250 MeV.
