Beta decay of 50Ni
Abstract.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 ($70\pm 20$)%.
