    Gamma-ray Spectroscopy of 62Ge

    The nuclear structure of 62Ge, beyond the N = Z line of stability, has been studied using γ-ray spectroscopy to unravel our understanding of nuclei around the mass region of A = 60. The experiment was conducted at the Radioactive Isotope Beam Factory (RIBF) in Japan, where 62Ge was produced from a neutron knock-out reaction by the reaction channel (12C,12CX)62Ge using a thin 12C target. Distinct low-lying bound excited states have been identified. Our finding from the singles γ-ray spectrum revealed three γ-ray transitions at 437(9), 748(15), and 947(10) keV energy. Evidence from the γγ coincidence analysis pointed out that the 748 keV transition is in coincidence with the 947 keV transition. Following a comparison between the theoretical models and the mirror nucleus, 62Zn, the level scheme for 62Ge was established. A 2+ state was identified unambiguously at 947 keV energy, which was tentatively reported from a single, previous experiment. The 2+ state was placed at 1695 keV energy due to the coincidence relationship between the 748 keV transition and the 947 keV transition. Subsequently, the 0+ state was placed tentatively at 1384 keV energy. This low-lying 0+ state can provide evidence for the occurrence of shape coexistence. This research adds to our understanding of atomic nuclei and provides information on the ongoing investigation of the intricacies of nuclear structure in order to construct reliable and unified nuclear models.
