The half-life of Cu-67 was newly determined by measurement of its 185 keV gamma-ray (48.7%) over the period of 13 d (approx. 5 x T-1/2). Cu-67 was prepared by deuteron irradiation of enriched Zn-70 targets. The Cu-67 half-life value which resulted from five independent measurements is estimated to be 61.81 (22) h.
