Collective rotation and vibration in neutron-rich {sup 180,182}Hf nuclei

Journal Article · · Physical Review. C, Nuclear Physics
High-spin states in neutron-rich {sup 180}Hf and {sup 182}Hf nuclei were populated through inelastic and transfer reactions with a {sup 136}Xe beam incident on a thin {sup 180}Hf target, and investigated using particle-{gamma} coincidence techniques. New collective band structures were observed, and previously known rotational and vibrational bands in these nuclei were extended to higher angular momenta. No obvious nucleon alignment was observed in the ground state band of either nucleus up to ({Dirac_h}/2{pi}){omega}=0.43 MeV, a significant delay compared to lighter even-even Hf isotopes. Woods-Saxon cranking calculations were performed to predict the nature of the first band crossings and shape evolution in {sup 180,182}Hf.
