Activations lasted for 2 hours and D431300100022 100nA beam current. Charge was measured in Faraday-cup D431300100023 and were compared with the monitor reactions. An D431300100024 agreement was found within 6%. Detector dead time was D431300100025 kept below 3%. The contribution of 64Cu produced in D431300100026 the Ni backing was checked and found to be negligible. D431300100027 Decay curve analysis of the annihilation peak was used D431300100028 to determine the 64Cu activity. Cross sections were D431300100029 normalized to 100% enrichment. D431300100030 Energy degradation was calculation by using the D431300100031 polynomial approximation of Andersen and Ziegler.

The uncertainty of the energy of the D431300100038 bombarding beam in the middle of each irradiated foil D431300100039 was estimated combining the uncertainties of the D431300100040 energy degradation depending on the thickness of the D431300100041 target foils in the stack and the energy straggling. D431300100042 The uncertainty on the median energy in the last foil D431300100043 was +-1.3MeV stack1, and +-1.7 stack2. D431300100044 (ERR-T) D431300100045 The overall uncertainty amounted to 13-17%.
