Abstract

The importance of deformation changes and the possible role of proton-neutron pairing correlations on the properties of paired band crossings at superdeformation in the A 60 mass region have been analyzed. The present analysis, supported in part by the cranked relativistic Hartree-Bogoliubov calculations for the SD band in 60Zn, suggests that when going from 60Zn to neighboring odd nuclei the properties of paired band crossings are strongly influenced by deformation changes. A number of questions related to the superdeformation in the A 30 mass region has been studied with the cranked relativistic mean field theory and the configuration-dependent cranked Nilsson-Strutinsky approach.
