The 88.5-sec activity observed among the products of the bombardment of nickel with 16-Mev alpha particles is assigned to Zn/sup 61/. The decay properties of this isotope were investigated by beta and gamma scintillation techniques and by coincidence measurements. Approximately 80% of the Zn/sup 61/ beta decays are to the ground state of Cu/sup 61/. The positron end point is 4.38 Mev which corresponds to a log ft of 5.2 and to an allowed transition. Gamma rays of 0. 8, 0.98, and 1.64 Mev were observed with intensities of 11.2, 2.9, and 6.2% of the positrons. There is some indication of gamma rays at 0.69 Mev and possibly other energies in lower intensities. A decay scheme is proposed which incorporates the above data into an existing level scheme of Cu/sup 61/ derived from (p, gamma ) experiments. (auth)
