INCOMPRESSIBILITY OF NUCLEAR-MATTER, AND COULOMB AND VOLUME-SYMMETRY COEFFICIENTS OF NUCLEUS INCOMPRESSIBILITY IN THE RELATIVISTIC MEAN-FIELD THEORY

The incompressibility of nuclear matter K, the Coulomb coefficient K-c , and the volume-symmetry coefficient K-vs of the nucleus incompressib ility are studied using the relativistic mean field theory. It is foun d that K = 300+/-50 MeV is necessary to account for the empirical valu es of K, K-c, and K-vs, simultaneously, if the scaling model is valid. The result is independent of the details of the sigma-meson self-inte raction and is almost independent of the strength of the omega-meson s elf-interaction. However, a wider range of K may be available, if devi ations from the scaling model are important.
