Properties of asymmetric semiin nite nuclear systems in the extended Thomas-Fermi model

Abstract

We start from the energy density of the Skyrme interaction and perform a leptodermous expansion for anasymmetric semiin nite nuclear system. We get a liquid drop model formula for the energy of such a system. We usethe obtained analytic formulae for volume, surface, and curvature energies to study the properties of asymmetric nuclearsystems. We also study the effect of the asymmetry parameter on the volume, surface, and curvature properties.
