Abstract
We measured the gamma ray yields of proton and alpha induced reactions on natural calcium in the form of CaO target. The production rates of 43Sc, 44Sc isotopes of medical imaging interest are determined. It is found that alpha production for E < 20 MeV are well suited for producing the 43Sc isotope, while proton beams of about 15–20 MeV yield both 43Sc and 44Sc isotopes in comparable amounts to be of use as prospective medical imaging by PET and associated photons.
