摘　　要：The back bending phenomenon observed in ^(87)Nb is interpreted very well within the approach of the triaxial cranking shell model(CSM)with the deformations determined by a total routhian surface calculation which includes the deformation drive of the high j quasiparticle orbits.It is suggested that the CSM is still valid for slightly deformed transitional nuclei if the configuration dependence of deformations is taken into account properly.
