| 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. |
