Nuclear Structure in $^7$$^8$Ge
ORAL
Abstract
Owing to the importance of the structure of $^{76}$Ge in interpreting double $\beta$ decay studies, the structures of adjacent nuclei have been of considerable interest. Recently reported features for the structures of $^{72,74,76}$Ge indicate both shape coexistence and triaxiality. New data for the excited states of $^{78}$Ge will be reported arising from Gammasphere studies of multinucleon transfer reactions between a $^{76}$Ge beam and thick heavy targets at the ATLAS facility at Argonne National Laboratory. The previously known yrast band is extended to higher spins, candidate levels for a triaxial sequence have been observed, and the associated staggering determined. The staggering in $^{78}$Ge found in this work is not in agreement with theoretical work\footnote{J.J Sun \it{et al.}, Phys. Lett B \textbf{734}, 308 (2014).}. Candidates for negative-parity states and seniority-four states will be discussed.
