Abstract
The relativistic microscopic optical potential, the Schrodinger equiva lent potential, and mean free paths of a nucleon at finite temperature in nuclear matter and finite nuclei are studied based on Walecka's mo del and thermo-field dynamics. We let only the Hartree-Fock self-energ y of a nucleon represent the real part of the microscopic optical pote ntial and the fourth order of meson exchange diagrams, i.e. the polari zation diagrams represent the imaginary part of the microscopic optica l potential in nuclear matter. The microscopic optical potential of fi nite nuclei is obtained by means of the local density approximation.
