    Deformed rotational cascades in 152Dy: Further evidence for shape coexistence at high spin
    (American Physical Society, 2000) Smith M.B.; Appelbe D.E.; Twin P.J.; Beausang C.W.; Beck F.A.; Bentley M.A.; Haas B.
    Two new rotational bands have been observed in the 152Dy nucleus following experiments performed using the EUROGAM ?-ray spectrometer. Several transitions have been observed that link these new bands into the known single-particle states. Using the Doppler shift attenuation method, the quadrupole moment of the previously-known rotational sequence has been measured. The value of Qband=3.85±0.06 e b confirms the deformed nature of this cascade. The structures of the three bands are discussed in terms of the occupation of both paired and unpaired orbitals, and are found to be in good agreement with theoretical calculations. The observation of two new bands further extends the concept of shape coexistence in the 152Dy nucleus.

    Delayed backbending in the ?h9/2 band of 187Ir
    (American Physical Society, 2003) Danchev M.; Balabanski D.L.; Yigitoglu I.; Akkus B.; Beausang C.W.; Bostan M.; Hartley D.J.
    High-spin states of 187Ir have been populated in the 176Yb(15N, 4n) reaction and measured with the YRAST Ball spectrometer. The ?h9/2 rotational band has been extended beyond the first alignment crossing, which was found at rotational frequency ??c ? 0.39 MeV. Two different scenarios for describing this crossing are considered: The alignment of an h9/2 proton or i13/2 neutron pair and it is concluded that a proton band crossing is more likely. A systematic study of the rotational alignment crossings in the ?h9/2 bands in the N=104, 106, 108 isotopes of 73Ta, 75Re, 77Ir, and 79Au is presented.
