Preparation of 67Cu via deuteron irradiation of 70Zn
A method for preparation of n.c.a. 67Cu based on deuteron irradiation of enriched 70Zn is presented. Cross-sections for 67Cu formation were determined by the stacked foil technique for deuteron energies in the range from 10 to 20 MeV for the first time. Irradiations of 70Zn foils were followed by radiochemical separation of 67Cu from the target material and co-produced radionuclidic impurities. The maximum cross-section value of 25.5 ± 2.2 mb was reached at 19 MeV. The integral yield in the energy window of 20 → 10 MeV on 95 % enriched 70Zn is estimated at 4.2 MBq/μAh (110 μCi/μAh) or 375 MBq/μA (10 mCi/μA) at saturation.
