Abstract: Background: The neutron microscopic optical potential is obtained by Green function method through nuclear matter approximation and local density approximation based on the effective Skyrme interaction. The presented Skyrme forces can not satisfactorily describe the nuclear reaction properties. Purpose: In the work, we propose a new set of Skyrme force parameterization of description nuclear reaction properties. Methods: The new Skyrme force parameterization is found by simultaneously fitting the characteristics of nuclear matter, the binding energy, charge radius, the neutron induced reaction cross sections and polarization data. These data include the total cross sections, nonelastic sections, elastic scattering angular distributions and analyzing powers for the target mass range 24≤A≤209 with incident neutron energies below 100 MeV. Results: The obtained Skyrme force is used to predict the neutron-actinide reactions with incident energies below 100 MeV. It is found that the calculations can give a satisfactory description of the experimental data. Conclusion: These results suggest that the obtained Skyrme force parameterization can not only describe the ground state properties, but for some quantities in the nuclear reaction. So, the obtained Skyrme force parameterization can be used to predict those data for the stable or unstable target in the mass range 23≤A≤239 with incident nucleon energies below 100 MeV.
