Abstract

We report the first observation of the 2+ isomer in Co52, produced in the β decay of the 0+, Ni52 ground state. We have observed three γ rays at 849, 1910, and 5185 keV characterizing the β de-excitation of the isomer. We have measured a half-life of 102(6) ms for the isomeric state. The Fermi and Gamow-Teller transition strengths for the β decay of Co52m to Fe52 have been determined. We also add new information on the β decay of the 6+, Co52 ground state, for which we have measured a half-life of 112(3) ms.
