摘要：

Decays of neutron-rich nuclei Zn-82,Zn-83 and Ga-82,Ga-83 produced in proton-induced fission of U-238 were studied at the Holifield Radioactive Ion Beam Facility using on-line mass separation and beta-gamma spectroscopy techniques. New gamma-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 beta transitions, and their structure was interpreted with new shell-model calculations. A beta-delayed neutron branching ratio of 69 +/- 7% was deduced for Zn-82 and revised beta-decay half-life values of Zn-82 [155(17)(20) ms] and Zn-83 [122(28) ms] were determined.
