Abstract

Separation energies as determined from nuclidic masses exhibit in a striking way the characteristic features of shell structure if plotted in a suitable three-dimensional scheme1. Our aim is to check this experimental behaviour numerically with the help of explicit shell-model calculations. It is shown that a rather good agreement is actually obtained if the independent particle levels of shell-structure are corrected with the help of the BCS pairing theory. This means that the direct interactions between individual nucleons are taken into account in a suitable approximation.
