COMPRESSIONAL PROPERTIES OF NUCLEAR-MATTER IN THE RELATIVISTIC MEAN-FIELD THEORY WITH THE EXCLUDED-VOLUME EFFECTS

The incompressibility and the skewness coefficient of nuclear matter a re studied by using the mean field theory with the excluded volume eff ects of the nucleons. The Coulomb coefficient li,and the volume-symmet ry coefficient of nuclear incompressibility are also calculated, with the aid of the scaling model. It is found that the excluded volume eff ects make it possible to fit the empirical data of the Coulomb coeffic ient K-c of nuclear incompressibility, even if the volume coefficient K is small (similar to 150 MeV). However, the symmetry properties favo r K=300+/-50 MeV as in the case of the mean field theory for point-lik e nucleons.
