Cyclotron Produced ~(67)Ga,a Potential Radionuclide for Diagnostic and Therapeutic Applications

摘要

Production cross-sections of the ~(nat)Zn(d,x)~(67)Ga reactions have been measured from a 24-MeV deuteron energy down to the threshold by using a stacked-foil activation technique combined with HPGe γ-ray spectrometry. An overall good agreement is found with some of the earlier measurements, whereas a partial agreement is obtained with the theoretical data extracted from the TENDL-2013 library. Physical thick target yield for the ~(67)Ga radionuclide was deduced using the measured cross-sections, and found in agreement with the directly measured yield available in the literature. This study reveals that a low deuteron energy (<11 MeV) cyclotron and an enriched ~(66)Zn target could be used to obtain ~(67)Ga in no carrier added form.
