摘要High-spin states in Yb-157 have been populated in the Sm-144( O-16,3n)Yb-157 fusion-evaporation reaction at a beam energy of 85 MeV. Two rotational bands built on the nu f(7/2) and nu h(9/2) intrinsic states, respectively, have been established for the first time. The newly observed nu f(7/2) band and previously known nu i(13/2) band in Yb-157 are discussed in terms of total Routhian surface methods and compared with the structures in the neighboring N = 87 isotones. The structural characters observed in Yb-157 provide evidence for shape coexistence of three distinct shapes: prolate, triaxial, and oblate. At higher spins, both the nu f(7/2) band and nu i(13/2) band in Yb-157 undergo a shape evolution with sizable alignments occurring.
