The mean square radius of the neutron distribution in the relativistic and nonrelativistic mean field models
Abstract
It is investigated why the root mean square radius of the point neutron distribution is smaller by about 0.1 fm in nonrelativistic mean field models than in relativistic ones. The difference is shown to stem from the different values of the product of the effective mass and the strength of the onebody potential in the two frameworks. The values of those quantities are constrained by the HugenholtzVan Hove theorem. The neutron skin is not a simple function of the symmetry potential, but depends on the nucleon effective mass.
