    "abstract": "The lightest superdeformed nuclei of the mass-60 region are described using\nthe Projected Shell Model. In contrast to the heaviest superdeformed nuclei\nwhere a coherent motion of nucleons often dominates the physics, it is found\nthat alignment of $g_{9/2}$ proton and neutron pairs determines the high spin\nbehavior for superdeformed rotational bands in this mass region. It is\npredicted that, due to the systematics of shell fillings along the even--even\nZn isotopic chain, observation of a regular superdeformed yrast band sequence\nwill be unlikely for certain nuclei in this mass region.",
