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 ${\mathit{K}}_{\mathit{c}}$, and the volume-symmetry coefficient ${\mathit{K}}_{\mathrm{vs}}$ of the nucleus incompressibility are studied using the relativistic mean field theory. It is found that K=300±50 MeV is necessary to account for the empirical values of K, ${\mathit{K}}_{\mathit{c}}$, and ${\mathit{K}}_{\mathrm{vs}}$, simultaneously, if the scaling model is valid. The result is independent of the details of the σ-meson self-interaction and is almost independent of the strength of the ω-meson self-interaction. However, a wider range of K may be available, if deviations from the scaling model are important. © 1996 The American Physical Society.
