    Evolving collective structures in the transitional nuclei W 162 and W 164
    (American Physical Society, 2016) Joss D.T.; Dracoulis G.D.; Higgins E.; Lewis M.; Thomson J.; Lane G.J.; Ertürk S.
    Excited states in the neutron-deficient nuclides W8874162 and W9074164 were investigated by using the ?-ray spectrometer Jurogam. A change in structure is apparent from the first rotational alignments in W162 and W164, whose rotationally aligned bands are interpreted as ?(h9/2)2 and ?(i13/2)2 configurations, respectively. The level schemes have been extended using recoil (-decay) correlations with the observation of excited collective structures. Configuration assignments have been made on the basis of comparisons of the deduced aligned angular momentum, as a function of rotational frequency, with the predictions of the cranked shell model. © 2016 American Physical Society.

    Spectroscopy of the neutron-deficient isobars 163 Re and 163 W using tagging techniques
    (American Institute of Physics Inc., 2008) Joss D.T.; Thomson J.; Scholey C.; Ertürk S.; Simpson J.; Page R.D.; Jones R.M.
    Selective tagging techniques have been used to establish new band structures in the transitional isobars 163 Re and 163 W. These nuclei were produced in the 106 Cd( 60 Ni, xp yn ?) reaction at a bombarding energy of 270 MeV. Prompt 7 rays were detected at the target position using the JUROGAM spectrometer while recoiling ions were separated by the RITU separator and implanted into the GREAT spectrometer At low spin, the yrast band of 163 Re is shown to be a strongly coupled collective band based on a proton h 11/2 configuration. In 163 W, the decay path of the 13/2 + isomeric state to the ground state has been identified and negative parity structures based on the ground state established. © 2008 American Institute of Physics.
