AbstractThe decay of Ga-72 has been investigated by means of gamma-ray spectroscopy. The Ga-72 nuclei were produced through the Ga-71(n, gamma)Ga-72 reaction. The Compton-suppressed spectrometer and High-purity Ge detectors have been used singly and in coincidence, respectively, to study gamma-rays in the beta(-) decay of Ga-72 to Ge-72. 93 gamma-rays, among which 7 were observed for the first time, were reported. A decay scheme of Ga-72 including 4 new levels is proposed which accommodates 87 of these transitions. Spins and parities for new levels are proposed from calculated log ft values, modes on the observed decay, and some nuclear reaction experiment results. Combining with the high-spin states observed by the in-beam gamma-ray spectroscopy of a previous decay work, the structure of the excited positive-parity yrast states of Ge-72 is discussed in the framework of the projected shell model.
