Abstract
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.
Highlights
A new relativistic Hartree-Fock approach with density-dependent σ, ω, ρ and π meson-nucleon couplings for finite nuclei and nuclear matter is presented
With a number of adjustable parameters comparable to that of relativistic mean field (RMF) Lagrangians, this density-dependent relativistic Hartree-Fock (RHF) (DDRHF) theory can give a good description of nuclear systems without dropping the Fock terms
It should be emphasized that this is the first time for the RHF approach to provide such a good quantitative description for the finite nuclei and nuclear matter
Summary
A new relativistic Hartree-Fock approach with density-dependent σ, ω, ρ and π meson-nucleon couplings for finite nuclei and nuclear matter is presented. The earlier relativistic Hartree-Fock (RHF) method led to underbound nuclei due to the missing of the meson self-interactions [19]. A new RHF approach which contains density-dependent meson-nucleon couplings is developed.
