摘要：
A new relativistic Hartree-Fock approach with density-dependent sigma, omega, rho and pi meson-nucleon couplings for finite nuclei and nuclear matter is presented. Good description for finite nuclei and nuclear matter is achieved with a number of adjustable parameters comparable to that of the relativistic mean field approach. With the Fock terms, the contribution of the pi-meson is included and the description for the nucleon effective mass and its isospin and energy dependence is improved. (c) 2006 Elsevier B.V.
