Gamma radiation in the decay of 67Ga

Abstract

The level scheme of 67Zn has been investigated by scintillation coincidence spectrometry. Angular correlation measurements of the 206 keV – 182 keV and 485 keV − 296 keV gamma cascades result in anisotropies of − 0.216 ± 0.008 and +0.27 ± 0.05.

The following spins have been allocated to the levels of 67Zn: ground state 5/2, 92 keV 3/2, 182 keV 5/2, 388 keV 3/2 and 870 keV 3/2. Evidence has been found for the existence of another level at 595 ± 10 keV, for which a spin of 5/2 is suggested. By delayed coincidences a value of 9.3 ± 0.2 μsec has been found for the half-life of the 92 keV metastable level in 67Zn.
