Nuclear spectra in a large scale shell model approach

Abstract

An iterative matrix diagonalization algorithm is briefly outlined. Its implementation in the spin uncoupled scheme for large scale shell model calculations is discussed with special attention at the convergence properties of the iterative process which establish the domain of applicability of the method. Within this domain, the method is able to generate a large number of eigenstates and, therefore, to provide an exhaustive description of low-lying nuclear spectra. The performance of the method is illustrated by its application to 130–134Xe isotopes.
