Production cross sections of Ga-68 and radioactive by-products in deuteron-induced reactions on natural zinc

摘要

Activation cross sections of the deuteron-induced reactions on natural zinc are studied for the production of the medical radionuclide Ga-68. The stacked foil activation method and the gamma-ray spectrometry were used. Co-produced radionuclides Ga-65,Ga-66,Ga-67, Zn-63,Zn-65,Zn-69m, Cu-61, and Co-58 are also investigated to evaluate amounts of impurities for practical use of Ga-68. Physical yields of the radionuclides were deduced from the measured cross sections.
