FINITE-NUCLEI PROPERTIES IN RELATIVISTIC DENSITY-DEPENDENT HARTREE-FOCK APPROACH

Finite nucleus properties are studied in a relativistic effective inte raction approach. Density dependent coupling constants of the meson-nu cleon interactions are adopted to incorporate the relativistic Brueckn er-Hartree-Fock results in the relativistic mean field (RMF) or relati vistic Hartree-Fock (RHF) approach. It is desired to remedy the defici encies of RMF and RHF without losing the features of the relativistic G matrix and at the same time retain the simplicity. The calculated gr ound state properties with the density dependent coupling constants ar e in a good agreement with experiment. The contribution of isovector m esons in RHF is discussed.
