Nuclear matter properties and relativistic mean-field theory
Abstract
Nuclear matter properties are calculated in the relativistic mean-field theory by using a number of different parameter sets. The result shows that the volume energy a1 and the symmetry energy J are around the acceptable values 16MeV and 30MeV, respectively; the incompressibility K0 is unacceptably high in the linear model, but assumes reasonable value if nonlinear terms are included; the density symmetry L is around 100MeV for most parameter sets, and the symmetry incompressibility Ks has positive sign which is opposite to expectations based on the nonrelativistic model. In almost all parameter sets there exists a critical point (
