Decay of Zinc 72

Abstract

Decay characteristics of ⁷²Zn was studied. ⁷²Zn was produced by the (γ, α) reaction on germanium and separated chemically. Radiations were measured with a scintillation spectrometer. Half life of this nuclide was determined to be 36.5 hours. The decay goes mainly with a 0.3-MeV beta component to a level which decays with a 145-keV gamma ray followed by a 18-keV gamma transition. Another weak component is followed by a 190-keV and the same 18-keV gamma transitions. Decay scheme is discussed.
