The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent. it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger. we compare our results with those in a simple method, where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy

The nucleon dbhf self - energy in the nuclear medium, therefore, can be calculated with the g matrix in the relativistic hartree - fock approximation. with the calculated nucleon self - energy in the dbhf, we extract nucleon effective interactions hi the framework of the relativistic mean field theory ( rmf ), which contains the effect of the nucleon - nucleon short - range correlation and information of the isospin structure. applying the effective interaction, which is composed of density dependent meson - nucleon coupling constants, we study the properties of finite nuclei and come to some useful conclusions
