Abstract：
The real relativistic microscopic optical potentials for ¹⁶O and ⁴⁰Ca have been calculated self-consistently in the framework of the Walecka model and the non-linear σ model.To compare with nonrelativistic optical potentials,the Schrodinger equivalent potentials are obtained.The differential cross sections and polarizations for the nucleon-nucleus elastic scatterings also have been calculated.It is found that the optical potentials obtained in the framework of the non-linear σ model are better than that in the Walecka model.
