Consistent Test of the Strutinsky-Nilsson Method

Abstract

The Strutinsky method for extracting the shell corrections from Nilsson single-particle energies is tested consistently within the constrained Hartree-Fock (CHF) framework. It is shown that a Nilsson potential, fitted to the CHF single-particle energies at one deformation, reproduces the CHF level ordering at other deformation surprisingly well. The shell corrections obtained from the Nilsson single-particle energies via the Strutinsky method are shown, however, to be unreliable by 30% on the average.
