摘要
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-<sup>40</sup>Ca scattering data at E<sub>p</sub>=200 MeV.The behavior of the optical potential witha complex effective mass for P-<sup>40</sup>Ca scattering at E<sub>p</sub>=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-<sup>16</sup>O,<sup>40</sup>Ca and <sup>208</sup>Pb scattering problem at E<sub>p</sub>=800 MeV.The calculated results,suchas cross sections and spin observables,are theoretical prediction and are compared withexperimental data.
