摘要： New parameter sets for the Lagrangian density in the relativistic mean field (RMF) theory, PK1 with nonlinear σ- and ω-meson self-coupling, PK1R with nonlinear σ-, ω- and ρ-meson self-coupling and PKDD with the density-dependent meson-nucleon coupling, are proposed. They are able to provide an excellent description not only for the properties of nuclear matter but also for the nuclei in and far from the valley of beta-stability. For the first time in the parametrization of the RMF Lagrangian density, the center-of-mass correction is treated by a microscopic way, which is essential to unify the description of nuclei from light to heavy regions with one effective interaction.
