The isotope [sup 52]Ni has been produced by fragmentation of a [sup 58]Ni beam at 68 MeV/nucleon on a nickel target and separated using the LISE spectrometer at GANIL. We have measured the half-life of [sup 52]Ni and the energies of [beta]-delayed protons emitted during the decay. Two proton lines have been observed at [ital E][sub [ital p]]=1.06[plus minus]0.05 MeV and 1.34[plus minus]0.06 MeV with branching ratios of 0.06[plus minus]0.01 and 0.11[plus minus]0.01, respectively. The measured half-life of [sup 52]Ni is [ital T][sub 1/2]=38[plus minus]5 ms. A partial decay scheme is proposed.
