Phys. Rev. C 68, 014303 (2003) [6 pages]Strongly coupled bands in the neutron-deficient nucleus 167ReReceived 23 April 2003; published 21 July 2003 Excited states in the neutron-deficient nucleus 167Re have been observed in a recoil-tagging experiment performed with the Jurosphere γ-ray spectrometer in conjunction with the RITU gas-filled recoil separator. The low-spin yrast band, based on a proton h11/2 orbital, comprises a strongly coupled band and exhibits significant signature splitting, indicative of a triaxial shape with γ<0°. At higher spin the rotational alignment of a pair of i13/2 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. © 2003 The American Physical Society URL:
