Absence of Low-Energy Shape Coexistence in ${}^{80}$Ge: The Nonobservation of a Proposed Excited 0${}_2^{+}$ Level at 639 keV

F. H. Garcia, C. Andreoiu, G. C. Ball +28

The ${}^{80}$Ge structure was investigated in a high-statistics $\beta$-decay experiment of ${}^{80}$Ga using the GRIFFIN spectrometer at TRIUMF-ISAC through $\gamma$, $\beta$-$e$, $e$-$\gamma$ and $\gamma$-…
