“…Detailed analysis of these interactions are beyond the scope of this paper and will not be discussed. Bands 11 and 12 were reported in our previous publication as TSD bands based on zero-and one-phonon wobbling excitations [5]. Bands 17 and 18 could not be linked to any known structures and, thus, their excitation energies, spins, and parities remain unknown.…”

“…The wobbling excitation mode, an experimental fingerprint for nuclei with stable triaxial shape, was predicted about 40 years ago [1], and has now been identified in 163 Lu [2,3], 165 Lu [4], and 167 Lu [5], possibly in 161 Lu [6], and recently in 167 Ta [7]. In addition, TSD structures based on quasiparticle excitations have also been observed in 163 Lu [8,9], 164 Lu [10], 164 Hf [11], 168 Hf [12,13], and a few neighboring nuclides.…”

Excited states in 167 Lu were populated in the 123 Sb( 48 Ca,4n) reaction at 203 MeV and decay γ-rays measured using the Gammasphere spectrometer array. Two triaxial strongly deformed bands were identified previously and interpreted as zero-and one-phonon wobbling excitations. As a result of more extensive band search, the level scheme has been considerably extended to include ten new rotational bands, and some 630 γ-ray transitions. A number of interband linking transitions were revealed, so that all but two bands could be connected with each other. Configurations are proposed for all new bands based on measured observables, with the help of Cranked Shell Model calculations. A γ-ray sequence, previously suggested as a triaxial strongly deformed band based on quasiparticle excitations coexisting with the wobbling excitation in the triaxial potential well, has now been determined to be a signature partner of a coupled band, associated with a normal deformed five-quasiparticle configuration. The possibility for two new bands being associated with triaxial deformation is discussed.
