英文摘要High-spin states in Pt-189 have been studied experimentally using the Yb-176(O-18,5n) reaction at beam energies of 88 and 95 MeV. The level scheme of Pt-189 has been revised significantly and extended to high-spin states. Rotational bands have been analyzed in the framework of triaxial particle-rotor model, and a gamma approximate to -30 degrees. triaxial shape and a near-prolate shape have been proposed to the nu i(13/2)(-1) and nu f(5/2)(p(3/2)) bands, respectively. Two Delta I = 2 transition sequences with similar energies have been observed, and they have been proposed to be associated with the nu i(13/2)(-2)nu f(5/2)(p(3/2)) configuration. The structure built on the nu i(13/2)(-2)nu f(5/2)(p(3/2)) configuration could be interpreted as a pair of pseudospin partners. The level energies in the pseudospin partner bands are well reproduced by the theoretical calculations of the triaxial particle-rotor model if a near-oblate shape is assumed.
