Аннотация

Excited states in the neutron-deficient nucleus ${}^{167}\mathrm{Re}$ have been observed in a recoil-tagging experiment performed with the Jurosphere $\ensuremath{\gamma}$-ray spectrometer in conjunction with the RITU gas-filled recoil separator. The low-spin yrast band, based on a proton ${h}_{11/2}$ orbital, comprises a strongly coupled band and exhibits significant signature splitting, indicative of a triaxial shape with $\ensuremath{\gamma}<0\ifmmode^\circ\else\textdegree\fi{}.$ At higher spin the rotational alignment of a pair of ${i}_{13/2}$ neutrons induces a transition to an axial prolate shape resulting in a drastic reduction of the signature splitting. Two other strongly coupled bands have been established and their structures are discussed in terms of quasiparticle configurations.
