The decay of ^<72>Ga has been investigated by means of γ-ray spectroscopy. The ^<72>Ga nuclei were produced through the ^<71>Ga(n, γ)^<72>Ga reaction. The Compton-suppressed spectrometer and High-purity Ge detectors have been used singly and in coincidence, respectively, to study γ-rays in the β-decay of ^<72>Ga to ^<72>Ge. 93 γ-rays, among which 7 were observed for the first time, were reported. A decay scheme of ^<72>Ga 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 experiment results. Combining with the high-spin states observed by the in-beam γ-ray spectroscopy of a previous decay work, the structure of the excited positive-parity yrast states of ^<72>Ge is discussed in the framework of the projected shell model.
