Establishing the ground-state spin of 71Kr
RADIOACTIVITY 71Kr(EC), (β+), (β+p) [from 9Be(92Mo, X), E=140 MeV/nucleon, followed by separation of fragments using A1900 fragment separator and a Radio Frequency Fragment Separator (RFFS) at the NSCL-MSU facility]; measured particle identification plot of implanted ions, Eγ, Iγ, E(p), I(p), (implants)β-coin, (implants)(β-delayed protons)-coin, (implants)γγ-coin, (implants)βγ-coin, T1/2 of decay of 71Kr; deduced absolute number of βγ-coin events, β events, absolute γ intensities, and intensities of β-delayed protons, logft for ground-state to ground-state superallowed β transition using SeGA array with 16 HPGe detectors for γ detection, and double-sided silicon-strip detector (DSSSDs) for particle detection. 71Kr; deduced Jπ and T1/2 of the ground state, decay branching ratios. 70Br; deduced T1/2 of the 0+ g.s. and 9+ isomer. 71Br, 70Se; deduced levels, J, π, β feedings, logft, I(p) feedings. Discussed structure of 71Kr and 71Br mirror nuclei. Comparison with previous experimental results.
