英文摘要: A new decomposition of the Dirac Bruckner- Hartree- Fock (DBHF) G matrix is used to study the isospin- dependent relativistic microscopic optical potential (RMOP). The optical potential of finite nuclei can be obtained in the local density approximation. The energy dependence of proton-nucleus scattering for the optical potentials of finite nuclei is discussed. The differential cross sections and the resolution power in the p + Ca-40 and p + Ph-208 at E-p less than 200 MeV are also calculated using the above RMOP. It is found that the calculated results agree with the experimental results. It should be emphasized that the ROMP obtained from DBHF G matrix without any free parameters could well describe the proton elastic scattering. This RMOP can also be used for unstable nuclei. From the results of the Ca isotopes, it is found that the isospin dependence is more important for the exotic nuclei.
