The beta and gamma measurements showed the presence of four gamma rays of energies 810 plus or minus and three beta groups of maximum energies 3.5 plus or minus 0.06 with a half life of 30 plus or minus 1 sec. Coincidence and sum spectrum studies showed that the 1080-kev gamma ray was in cascade with the 800- and 1240-kev gamma rays, and that the 1080-kev gamma ray was in coincidence with 3.5-, 2.7 and 2.25-Mev beta particles. A decay scheme is proposed, and a /68/Cu--/sup 68/Zn mass difference of 4.58 Mev is obtained.
