论文摘要
$^{80} $ ge结构在高统计级$β$ -Decay实验中进行了$^{80} $ ga的使用，使用triumf-isac通过$γ$，$β$ - $ e $，$ e $，$ e $ - $γ$和$γ$γ$和$γ$ - $γ$γ$ Spectroscopy的Griffin光谱仪进行了研究。没有发现最近报道的0 $ _2^{+} $ 639-kev级别的证据，建议是$^{80} $ ge中低能形状共存的证据。大规模壳模型计算以$^{78,80,82} $ ge放置$ 0^{+} _ {2} $ LEVEL $^{80} $ ge in 2 \，Mev，Mev。新的实验证据与壳模型预测相结合，表明$^{80} $ ge中不存在低能形状共存。
The $^{80}$Ge structure was investigated in a high-statistics $β$-decay experiment of $^{80}$Ga using the GRIFFIN spectrometer at TRIUMF-ISAC through $γ$, $β$-$e$, $e$-$γ$ and $γ$-$γ$ spectroscopy. No evidence was found for the recently reported 0$_2^{+}$ 639-keV level suggested as evidence for low-energy shape coexistence in $^{80}$Ge. Large-scale shell model calculations performed in $^{78,80,82}$Ge place the $0^{+}_{2}$ level in $^{80}$Ge at 2\,MeV. The new experimental evidence combined with shell model predictions indicate that low-energy shape coexistence is not present in $^{80}$Ge.
