Abstract：
Many superdeformed bands have been observed in A=120—140 mass region.The occupation of vi _13/2orbit is generally considered as the important cause.vi _13/2band head energy and deformation of odd N nuclei for Z=56—64 and N=69—77 has been calculated systematically with our modified Nilsson κ,μ parameters in this mass region.Results show that on the one hand,the occupation of vi _13/2orbit does favor the superdeformation tendency of nuclei; and on the other hand,the possible candidates of low lying vi _13/2configuration for experimental observation.
