Abstract：
A semiempirical expression for the excitation function for (n,p) reaction were obtained on the basis of evaporation and exciton models with the energies range up to 20 MeV. Within the nuclide of 12≤A≤209, the adjusted parameter of the semiempirical expression was investigated, the parameter is dependent on the atomic number, mass number of the target nuclide, and the energy of the incident neutron. The predictions of the excitation function for (n,p) reaction are good agreement with the experimental data.
