Abstract

The decay of the Zn71 isomers has been reinvestigated using scintillation counter techniques. Samples of enriched Zn70 were exposed to reactor neutrons. Gamma rays of 120±5, 390±10, 510±5, 680±20, 920±10, 1120±10, and 1630±10 kev were found in the decay of the 2.45±0.10-min isomer. A beta ray group to the ground state of Ga71 with energy of 2.61±0.05 Mev was found from the 2-min isomer. Gamma rays of 390±5, 490±5, and 610±5 kev were found to be in cascade in the 4.0±0.1-hr isomer and to be fed by a single beta group of 1.46±0.05 Mev. A decay scheme for the Zn71 isomers is proposed.
