Neutron Skin Thickness of Nuclei and Effective Nucleon–NucleonInteractions

Abstract

The Skyrme energy density functional is applied to study the groundstate properties of a series of finite nuclei. The charge rms radii,neutron rms radii, and the neutron skin thickness for some nuclei arecalculated and compared with the experimental data. The constraint onthe effective interactions, especially, the density dependence of theisospin-dependent part of Skyrme interactions is extracted by the dataof neutron skin thicknesses of 208Pb and isotopes of Sn.
