摘　　要：The relativistic microscopic optical potential (RMOP) in the nucleon-nucleus scattering is studied in the framework of the Dirac Brueckner Hartree-Fock (DBHF) approach. The real part of theThe relativistic microscopic optical potential （RMOP） in the nucleon-nucleus scattering is studied in the framework of the Dirac Brueckner Hartree-Fock （DBHF） approach. The real part of the nucleon self-energy in asymmetric nuclear matter is calculated with the G-matrix, while the imaginary part is obtained from the polarization diagram. Nuclear optical potentials in finite nuclei are derived from the nucleon self-energies in asymmetric nuclear matter through a local density approximation. The RMOP is applied to study the nucleon scattering off stable nuclei and nucleon effective mass. A satisfactory agreement with the experimental data is found.
