Abstract
High-spin states in179Re have been populated by the165Ho(18O, 4n) and170Er(14N,5n) reactions. A level scheme is constructed from the studies ofγγ-coincidences using anti-Compton spectrometer arrays. The previously known 5/2+[402], 1/2− [541] and 9/2− [514] bands have been extended to 35/2+, 45/2− and 39/2−, respectively. In addition a 1/2+ [660] band, a three-quasiparticle band and two isomers were established. Furthermore several level sequences were identified decaying into the 5/2+ [402] and 1/2− [541] bands. This allowed to determine the excitation energy of the 9/2− member of the latter band. The band crossing features of the bands have been explained as the rotation alignment of ani 13/2 quasineutron pair taking into account shape changes.
