Search for the ⁷³Ga ground-state doublet splitting in the β decay of ⁷³Zn

RADIOACTIVITY ⁷³Zn(β^-)[from U(p, F), E=1.4 GeV]; measured Eγ, Iγ, βγ- and γγ-coin, half-life of ⁷³Zn from γ-decay curves, level half-lives by fast-timing βγγ(t) technique using Resonance Ionization Laser Ion Source (RILIS) and magnetic high-resolution mass separator (HRS) at ISOLDE-CERN. ⁷³Ga; deduced levels, ground state doublet, J, π, β feedings, logft, B(M1), B(E2). ⁷³Zn(IT); measured Eγ, half-life of the isomer; deduced no evidence for a 42-keV transition from the isomer. Comparison with previous measurements, and with shell-model calculations. Systematics of level structure in ^71,73,75Ga.
