摘要：

Neutron total and differential elastic scattering cross sections for Fe-56 and U-238 nuclei were calculated from different global spherical optical potential (SOP) sets. The total cross sections sigma(t) for these nuclei for different neutron energies were calculated. The results were compared with those of the experimental data obtained from the EXFOR data file to select the best-fit potential parameters. In addition, the angular distributions of elastically scattered neutrons at different neutron energies were also studied. It was observed that the best overall fit to the experimental values of the total cross sections and angular distributions are obtained from sop parameter set 2 of Wilmore and Hodgson for Fe-56 and set 12 of Bersillon and Cindro for U-238.
