英文摘要 | A phenomenological momentum-independent (MID) model is constructed to describe the equation of state (EOS) for isospin asymmetric nuclear matter, especially the density dependence of the nuclear symmetry energy E (sym)(rho). This model can reasonably describe the general properties of the EOS for symmetric nuclear matter and the symmetry energy predicted by both the sophisticated isospin and momentum dependent MDI model and the Skyrme-Hartree-Fock approach. We find that there exists a nicely linear correlation between K (sym) and L as well as between J (0)/K (0) and K (0), where L and K (sym) represent, respectively, the slope and curvature parameters of the symmetry energy at the normal nuclear density rho (0), while K (0) and J (0) are, respectively, the incompressibility and the third-order derivative parameter of symmetric nuclear matter at rho (0). These correlations together with the empirical constraints on K (0), L and E (sym)(rho (0)) lead to an estimation of -477 MeV a parts per thousand currency sign K (sat,2) a parts per thousand currency sign -241 MeV for the second-order isospin asymmetry expansion coefficient for the incompressibility of asymmetric nuclear matter at the saturation point. |
