Abstract：
The influence of the parameters of the relativistic optical potential on the nucleon scattering properties, such as cross sections, angular distributions and spin observables etc., is studied based on a set of global Dirac phenomenological optical potential. It is shown that, in contrast with the case at low energies, the total scattering cross sections vary slowly with the energy and depend weakly on the potentials at E_p <300 MeV. The differential cross sections and spin observables depend not only on the volume integrals of the optical potentials, but also on their strengths and shapes. The applicability of the relativistic microscopic optical potential based on the Walecka model in the medium energy region is also discussed in this paper.
