Excited states in the neutron-deficient nucleus 161
72Hf89 have been populated using the 118Sn(48Ti,5n)
161Hf and 110Pd(56Fe,5n)
161Hf fusion-evaporation reactions at 240 and 270 MeV, respectively. The level scheme for 161Hf
has been extended with the observation of new band structures and an I π = (13/2+) isomeric state with a half-life
of 4.8(2) μs has been identified. The decay path from this isomer to the (7/2−) ground state is established. The
yrast band, based on the (13/2+) isomeric state, is extended up to (73/2+) and side band structures are identified
up to (69/2−) and (55/2−). Quasiparticle assignments for these rotational structures are made on the basis of
their alignment properties and Woods-Saxon cranked shell-model calculations.
