摘要：
Selected high-spin bands in A = 120-170 nuclei are interpreted within the configuration-constrained Cranked Nilsson-Strutinsky formalism with pairing neglected (CNS) and with pairing included (CNSB). A few bands in Lu/Hf nuclei which have been interpreted as formed at large triaxial deformation are reinterpreted as rotational bands at small deformation approaching termination. The differences between the linked high-spin rotational bands in Xe-125,Xe-126 are explored, suggesting that the bands in Xe-126 terminate high above yrast at close to spherical shape.
