报告简介：
The relativistic optical model potential (OMP) for nucleon-nucleus scattering is investigated in the framework
of the Dirac-Brueckner-Hartree-Fock (DBHF) approach using the Bonn-B one-boson-exchange potential for the
bare nucleon-nucleon interaction. The nucleon self-energies in the nuclear medium are derived from the DBHF approach based on the projection techniques within the subtracted T -matrix representation. The Dirac potentials as well as the corresponding Schroedinger equivalent potentials for finite nuclei are evaluated in the improved local density approximation. Systimatic analyses of the nucleon-nucleus scatterings are studied with this microscopic approach of the OMP and compared to the experimental data, as well as the results obtained with a phenomenological OMP. A good agreement between the theoretical results and the measurements can be achieved.
