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 ($70\pm 20$)%.
