SELF-CONSISTENT STUDY OF THE SURFACE THICKNESS OF NUCLEAR DENSITIES AND SINGLE-PARTICLE POTENTIALS

The surface thickness of nuclear densities and single-particle potentials calculated self-consistently in the energy-density formalism is studied for a set of nuclei near the stability line. The surface is divided into an internal part (inside the half-density radius) and an external part (outside the half-density radius). The variations of the thickness of these two parts with the nucleon number are examined. Shell effects and differences between the two parts are studied.
