Configuration-seniority spectral distributions in Ni62

TLDR: In this article, the goodness of the symplectic symmetry is discussed by investigating the distributions with fixed seniority in every orbit, and the results compared with those of the shell model.

Abstract: 2014 Configuration-seniority spectral distributions are used to analyse some properties of Ni62, and the results compared with those of shell model. The goodness of the symplectic symmetry is discussed by investigating the distributions with fixed seniority in every orbit. LE JOURNAL DE PHYSIQUE LETTRES Classification Physics Abstracts 4.161 TOME 37, JANVIER 1976, During the last few years significant progress has been made in the study of the spectra of complex nuclei involving a large number of configurations, by the introduction of the spectral distribution method [1-3]. Applications of this method to the calculation of low excitation spectra and level densities and to the study of symmetries have been carried out in some cases. In a series of papers we intend to study the symplectic symmetry, connected with the seniority quantum number, for systems of n identical nucleons distributed in a finite set of levels with total degeneracy 2 ~2. In a former work [4] we studied fixed generalized seniority distributions, associated with the chain of groups V(2 0) ::) Sp (2 ~2). In this paper we give preliminary results for configuration-seniority distributions, connected with the chain of groups wherein the averages are taken over subspaces characterized by
