Cranked Nilsson-Strutinsky vs the spherical shell model: A comparative study of pf-shell nuclei

Juodagalvis, A.; Ragnarsson, Ingemar LU and Åberg, Sven LU (2006) In Physical Review C: covering nuclear physics 73. p.1-044327
Abstract
A comparative study is performed of a deformed mean field theory, represented by the cranked Nilsson-Strutinsky (CNS) model and the spherical shell model. Energy spectra, occupation numbers, B(E2) values, and spectroscopic quadrupole moments in the light pf-shell nuclei are calculated in the two models and compared. The result is also compared to available experimental data which are generally well described by the shell model. Although the Nilsson-Strutinsky calculation does not include pairing, both the subshell occupation numbers and quadrupole properties are found to be rather similar in the two models. It is also shown that "unpaired" shell model calculations produce energies similar to those from the CNS. The role of the pairing... (More)
