The decay of the Zn/sup 71/ isomers was reinvestigated using scintillation counter techniques. Samples of enriched Zn/sup 70/ were exposed to reactor neutrons. Gamma rays of 120 plus or minus 5, 390 plus or minus 10,510 plus or minus 5,680 plus or minus 20,920 plus or minus 10,1120 plus or minus 10, and 10 kev were found in the decay of the 2.45 plus or minus 0.10- min isomer. A beta ray group to the ground state of Ga/sup 71/ with energy of 2.61 plus or minus 0.05 Mev was found from the 2-min isomer. Gamma rays of 390 plus or minus 5, 490 plus or minus 5, and 610 plus or minus 5 kev were found to be in cascade in the 4.0 plus or minus 0.1-hr isomer and to be fed by a single beta group of 1.46 plus or minus 0.05 Mev. A decay scheme for the Zn/ sup 71/ isomers is proposed. (auth)
