Search for High-Spin Triaxial Strongly Deformed Bands in $^{166}$W

High-spin triaxial strongly deformed (TSD) structures, including families of wobbling bands, have been observed in several Lu and Ta Isotopes near $A \sim 165$, and in $^{164,168}$Hf as well.\footnote{J. C. Marsh {\it et al}., Phys. Rev. C {\bf 88}, 041306(R) (2013).} The nuclide $^{166}$W is close to the proton and neutron shell gaps at large triaxiality. Theoretical studies suggest that the elevated yrast line of $^{166}$W, an $N = 92$ isotone, may reduce the excitation energy of the predicted TSD structure relative to its normal deformed yrast line, resulting in an increased population of the TSD bands. A Gammasphere experiment has been performed at the ATLAS facility to search for such structures through the $^{110}$Pd($^{60}$Ni,4n) reaction. Previously known bands have been extended to higher spins, and several new bands have been identified. Further data analysis is in progress, results will be presented.
