Abstract：
The density dependent coupling constants of nucleon-meson interactions are adopted to incorporate the self-energy of relativistic Brueckner-Hartree-Fock calculations in the relativistic mean field approach. The density dependent interaction takes the N-N correlations into account. This density dependet interaction is employed to study the ground state properties of finite nuclei such as single particle levels, charge raddi and the binding energies per nucleon. The results calculated are in a good agreement with the experimental data. A comparison with the results obtained by other models is also presented.
