Abstract:Copper / Half-life / 67 CuSummary. The half-life of 67 Cu was newly determined by measurement of its 185 keV γ -ray (48.7%) over the period of 13 d (approx. 5 × T 1/2 ). 67 Cu was prepared by deuteron irradiation of enriched 70 Zn targets. The 67 Cu half-life value which resulted from five independent measurements is estimated to be 61.81 (22) h.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
