摘要

【正】 Relativistic microscopic optical potential of the nucleon-nucleus scattering isobtained from the relativistic Brueckner-Bethe-Goldstone（RBBG）equation.The com-plex effective mass of a nucleon in the medium is phenomenologically determined by afit to P-⁴⁰Ca scattering data at E_p=200 MeV.The behavior of the optical potential witha complex effective mass for P-⁴⁰Ca scattering at E_p=200 MeV is compared with that ofa real effective mass.The relativistic microscopic optical potentials with both the com-plex and real effective masses,obtained from the RBBG equation,are used to studyp-¹⁶O,⁴⁰Ca and ²⁰⁸Pb scattering problem at E_p=800 MeV.The calculated results,suchas cross sections and spin observables,are theoretical prediction and are compared withexperimental data.
