Abstract

Directional correlation measurements were made on the 1700–1077 keV gamma cascade in 68Zn using a scintillation coincidence spectrometer. Correlations were observed using different thickness of absorber in front of the counters in order to attenuate the effects of annihilation radiation on the correlation. The correlation in each case was expressed in the form W(θ) = 1+A2P2(cos θ)+A4P4(cos θ). The variations of A2 and A4 with absorber thickness and arguments based on beta-decay theory suggest that the spin sequence 2(1, 2) 2(2)0 is appropriate for the cascade. The spin and parity 2+ is tentatively assigned to a 2780±18 keV level in 68Zn.
