英文摘要: The spectroscopy of Yb-157 has been studied via Sm-144(O-16, 3n)Yb-157 fusion-evaporation reaction. The properties of bands associated with the vi(13/2) orbital and vh(9/2) orbital in Yb-157 are analyzed in comparison with the triaxial particle-rotor-model calculations. The characters of signature splitting for both positive-parity vi(13/2) and negative-parity vh(9/2) bands in Yb-157 and heavier odd-A Yb isotopes are discussed. The newly observed bands 1 and 2 in Yb-157 are suggested to be the signature partners of the vh(9/2) band. A systematic study of the band crossing frequencies associated with the i(13/2) neutron-pair and h(11/2) proton-pair alignments for the Yb isotopes, as well as the Er and Hf isotopes, are made.
