Table 1 Common production paths and decay properties of 61Cu, 64Cu and 67Cu. All nuclear data was acquired from NuDat (Brookhaven National Laboratory 2020a) and Qcalc (Brookhaven National Laboratory 2020b). “Q” notes q-value
From: Automated, cassette-based isolation and formulation of high-purity [61Cu]CuCl2 from solid Ni targets
