Relativistic and Non-Relativistic Mean Field Investigation of the Superdeformed Bands in 62Zn

Abstract

Following the first discovery of the superdeformed (SD) band in the A∼ 60 mass region, we calculate several low-lying SD bands in 62Zn using the relativistic mean field and Skyrme-Hartree-Fock models. Both models can reproduce the experimental moment of inertia very well, but we find that the calculated band, which corresponds to the experimentally observed band, does not become the lowest one. This trend is common among all the parameter sets which are widely used in RMF and SHF studies, and it seems to be connected with the fact that the position of the g9/2 level is not reproduced in 56Ni.
