Nuclear Matter Properties and Relativistic Mean Field Theory with Excluded Volume Effects

Abstract

Nuclear matter properties are calculated in the relativistic mean field theory with the excluded volume effects by using a number of different parameter sets. The results show that the incompressibility K0 assumes reasonable value; the density symmetry L is around 100 MeV, and the symmetry incompressibility Ks has positive sign in models without EVE, but may be negative if EVE is took into account. In almost all parameter sets there exists a critical point where the incompressibility equals zero, but for a few parameter sets there is no critical point and the pure neutron matter is predicted to be bound.
