Abstract：
Relativistic microscopic optical potential of a nucleon above the fermi sea based on Walecka's model is used to systematically analyze the proton elastic scattering from nuclei at energies below 300MeV.It is shown that the experimental data of differential cross sections,analyzing powers and spin rotation functions are reproduced satisfactorily except for large angles.This simple model might be used in the nuclear transport theory and heavy ion collision to take account of both nuclear medium and relativistic effects.
