Title: Reexamining Gamow-Teller decays near Ni 78

Abstract

Decays of neutron-rich nuclei 82,83Zn and 82,83Ga produced in proton-induced fission of 238U were studied at the Holifield Radioactive Ion Beam Facility using on-line mass separation and β–γ spectroscopy techniques. New γ-ray transitions were identified and level schemes, which include states at high excitation energies in the range between 3–7 MeV were constructed. These high-energy levels were identified to be populated through allowed Gamow-Teller β transitions, and their structure was interpreted with new shell-model calculations. Furthermore, a β-delayed neutron branching ratio of 69±7% was deduced for 82Zn and revised β-decay half-life values of 82Zn [155(17)(20) ms] and 83Zn [122(28) ms] were determined.
