Abstract

The β decay of the N=51 nucleus Zn81 was studied by means of β-γ spectroscopy and from isotopically pure beams produced at the Holifield Radioactive Ion Beam Facility (HRIBF). We observe several competing β transitions populating Ga81 that are interpreted as allowed Gamow-Teller decays to positive parity, core excited states, and first-forbidden decays to negative parity states. The measured β-decay pattern suggests an assignment of Iπ=5/2⊃+ for the Zn81 ground state. The systematics of core excited states in N=50 isotones indicate a strengthening of the N=40 subshell gap near Ni78.
