    We report the first observation of the 2+ isomer in 52Co, produced in the β decay of the 0+, 52Ni ground state. We have observed three γ-rays at 849, 1910, and 5185 keV characterizing the β deexcitation 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 52mCo to 52Fe have been determined. We also add new information on the β decay of the 6+, 52Co ground state, for which we have measured a half-life of 112(3) ms.
