Surface tension in a compressible liquid-drop model: Effects on nuclear density and neutron skin thickness

Abstract

We examine whether or not the surface tension acts to increase the nucleon density in the nuclear interior within a compressible liquid-drop model. We find that it depends on the density dependence of the surface tension, which may in turn be deduced from the neutron skin thickness of stable nuclei.
