64Ni(d,2n)64Cu Excitation function measurements performed on natNi.
Thick target yield measurements in 15-19 MeV window performed with both natNi and 64Ni (96% enriched). Yield ratios compare very well with the 64Ni abundance ratios.
Preliminary calculation by evaluator indicates that the measured thick target yield reported for natNi is almost 2X higher than the yields predicted on the basis of their reported cross sections.
Validation using thick target yield data was required
