Search for the Exotic Wobbling Mode in $^{171}$Re*

The observation of a wobbling band is a strong indication that a nucleus possesses triaxial deformation. The wobbling mode has been found in the $Z\approx 72$, $N\approx 94$ region in five Lu isotopes and in $^{167}$Ta and is associated with the $i_{13/2}$ band. In order to determine the role of the proton Fermi surface, an experiment was conducted to search for the wobbling mode in $^{171}$Re. High-spin states in $^{171}$Re were produced in the $^{120}$Sn($^{55}$Mn, $4n$) reaction and the gamma rays were detected with Gammasphere. Several bands have been found to feed into the $i_{13/2}$ structure, and their characteristics will be assessed to determine if these sequences are associated with wobbling. The implications of this result on the region of triaxiality will be discussed.
