Abstract
The spectroscopy of Yb has been studied via Sm(O,)Yb fusion-evaporation reaction. The properties of bands associated with the orbital and orbital in Yb are analyzed in comparison with the triaxial particle-rotor-model calculations. The characters of signature splitting for both positive-parity and negative-parity bands in Yb and heavier odd-A Yb isotopes are discussed. The newly observed bands 1 and 2 in Yb are suggested to be the signature partners of the band. A systematic study of the band crossing frequencies associated with the neutron-pair and proton-pair alignments for the Yb isotopes, as well as the Er and Hf isotopes, are made.
