Mean field studies of high-spin properties in the $A\sim 30$ and 60 regions of superdeformation

摘要

The importance of deformation changes and the possible role of proton-neutronpairing correlations on the properties of paired band crossings atsuperdeformation in the $A\sim 60$ mass region have been analyzed. The presentanalysis, supported in part by the cranked relativistic Hartree-Bogoliubovcalculations for the SD band in $^{60}$Zn, suggests that when going from$^{60}$Zn to neighboring odd nuclei the properties of paired band crossings arestrongly influenced by deformation changes. A number of questions related tothe superdeformation in the $A\sim 30$ mass region has been studied with thecranked relativistic mean field theory and the configuration-dependent crankedNilsson-Strutinsky approach.
