Abstract：
The isospin-dependence of the relativistic microscopic optical potential is investigated in the Dirac Brueckner-Hartree-Fock approach. The isospin part of the microscopic optical potential is emphasized. A local density approximation is adopted for finite nuclei. Taking ²⁰⁸Pb as example,the difference between proton and neutron optical potentials is studied and compared with the phenomenological Lane Model potential.
