“…The impulse approximation which is used in most of these investigations is rather successful in particular for proton scattering at energies above 100 MeV. Medium effects are typically derived from nuclear matter and taken into account in a local density approximation [28].…”

The momentum dependence of the mean-field contribution to the real part of the optical model potential is investigated employing realistic nucleon-nucleon interactions. Within a non-relativistic approach a momentum dependence originates from the non-locality of the Fock exchange term. Deducing the real part of the optical model from a relativistic Dirac Brueckner Hartree Fock approximation for the self-energy of the nucleons yields an additional momentum dependence originating from the non-relativistic reduction of the self-energy. It is demonstrated that large Fock terms are required in the non-relativistic approach to simulate these relativistic features. A comparison is made between a local density approximation for the optical model and a direct evaluation in finite nuclei.

“…It is necessary to investigate the optical potential microscopically in a more fundamental theory. Studies of the relativistic microscopic optical potential (RMOP) in the past few years were based on several models, such as the RMF [5,6], the relativistic Hartree-Fock (RHF) [7], and the Dirac-Brueckner-Hartree-Fock (DBHF) [8][9][10] approaches. The nucleon self-energies were calculated in symmetric nuclear matter, and the isospin dependence was usually neglected.…”

“…The nucleon self-energies were calculated in symmetric nuclear matter, and the isospin dependence was usually neglected. A reasonable description of the differential cross sections, analyzing powers and spin-rotation functions of proton scattering off stable nuclei has been achieved in an energy range of 50-500 MeV without readjusting parameters [7,9,10].…”

PTHThe relativistic microscopic optical potential (RMOP) is studied within the framework of the Dirac-Brueckner-Hartree-Fock (DBHF) approach. A new decomposition of the Dirac structure of nuclear self-energy in the DBHF is extended to asymmetric nuclear matter calculations. A nucleon effective interaction is introduced to reproduce the results of the G matrix. The real part of nucleon self-energy in asymmetric nuclear matter is calculated with the G matrix in the Hartree-Fock approach, while the imaginary part is obtained from the polarization diagram. Nuclear optical potentials in finite nuclei are derived from the self-energies in asymmetric matter through a local-density approximation. The differential cross sections and the analyzing powers in p+40Ca and p+208Pb elastic scattering at Ep<=200 MeV are studied with these RMOPs. A satisfactory agreement with the experimental data is found. This is achieved without readjusting phenomenologically the RMOP derived from the DBHF plus polarization diagram
