Relativistic and Non-Relativistic Mean Field Investigation of the Superdeformed Bands in Neutron-Deficient Zn Isotopes

Following the experimental discovery of the superdeformed(SD) band in Zn, we calculate several low-lying SD bands in neutron-deficient 30Zn isotopes using Relativistic Mean Field model. For comparison, we also perform nonrelativistic Skyrme-Hartree-Fock calculation of the SD bands in Zn. Both models give somewhat smaller moments of inertia than the observed ones, but we can see some qualitative differences in the results of these two models, which seem to be coming from the difference of the order of single-particle levels through that in the equilibrium deformation.
