Description
High-spin states in neutron-rich 180Hf and 182Hf nuclei were populated through inelastic and transfer reactions with a 136Xe beam incident on a thin 180Hf target, and investigated using particle-γ 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 (ℎ/2π)ω=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 180,182Hf
