Beta Decay of $^{80,82}$Ga with GRIFFIN and Shape Coexistence in $^{80,82}$Ge

Shape coexistence in atomic nuclei, the existence of structures with different degrees of deformation in a narrow energy range, is an exciting phenomenon present across the chart of nuclides. In our experiment, we searched for evidence of shape coexistence in $^{80}$Ge and $^{82}$Ge by investigating their respective intruder 0$_2$_$^{+}$ states. The experiment was performed at the ISAC-TRIUMF facility where $^{80}$Ge and $^{82}$Ge isotopes were formed from the $\beta$-decay of their parent isotopes, $^{80}$Ga and $^{82}$Ga, respectively. The two Ga beams were produced by the ISOL technique using a 480 MeV proton beam with a 10 $\mu$A current colliding with a UC$_x$ target. A specialized ion source was used to suppress Rb contamination. The $\beta$-decay was measured using the GRIFFIN spectrometer which was equipped with 15 HPGe detectors for $\gamma$-ray detection, a ZDS plastic scintillator for $\beta$-tagging, the PACES array which has 5 Si(Li) detectors for conversion electron spectroscopy and 8 LaBr$_3$ scintillators for fast timing measurements of nuclear levels. Using this array, correlated $\gamma$-$\gamma$, $\gamma$-electron and electron-electron data have been acquired simultaneously, providing a detailed level scheme for $^{80}$Ge. Preliminary results will be presented.
