Beta decay of 50Ni

The very neutron-deficient isotope 50Ni was produced in fragmentation reactions between a \(650\cdot\) A MeV 58Ni beam and a 9Be target. For the first time the decay of this nucleus was investigated, leading to the determination of the half-life as 12+3-2 ms and the branching ratio for \(\beta\)-delayed proton emission of (\(70\pm 20\))%.
