Abstract

In the σ-ω-ρ model of the relativistic mean field theory with nonlinear σ-meson self-interaction, the effective nucleon mass M^* is discussed with relation to the symmetry incompressibility K_s of nuclear matter, based on the model parameters fitted to nuclear matter properties. It is shown that M^* is larger than 0.73M, if K_s is assumed to be negative and the nuclear matter incompressibility K₀ is kept less than 300 MeV. Furthermore, the field system is shown to be stable, as the σ-meson self-interaction energy is lower bounded in this parameter region.
