| 摘 要： | The decay of ^72Ga has been investigated by means of γ-ray spectroscopy. The 72Ga nuclei were produced through the ^71Ga(n, γ)^72Ga reaction. The Compton-suppressed spectrometer and high-purity Ge detectors have been used singly and in coincidence, separately, to study γ-rays in the β-decay of ^72Ga to ^72Ge. Ninety-three events of γ-rays were reported, of which 7 were observed for the first time. A decay scheme of ^72Ga including 4 new levels is proposed which accommodates 87 of these transitions. Spins and parities for new levels are proposed from calculated logft values, modes on the observed decay, and some nuclear reaction experimental results.

| Abstract: | The decay of $^{72}$Ga has been investigated by means of $gamma$-ray spectroscopy. The $^{72}$Ga nuclei were produced through the$^{71}$Ga(n, $gamma)^{72}$Ga reaction. The Compton-suppressedspectrometer and high-purity Ge detectors have been used singly and incoincidence, separately, to study $gamma$-rays in the $beta ^{-}$decay of $^{72}$Ga to $^{72}$Ge. Ninety-three events of $gamma$-rayswere reported, of which 7were observed for the first time. A decay scheme of $^{72}$Ga including 4new levels is proposed which accommodates 87 of these transitions. Spins andparities for new levels are proposed from calculated log$ft$ values, modes onthe observed decay, and some nuclear reaction experimental results. |
