The excitation functions of proton induced reactions on Sc targets (100% 45Sc), leading to the formation isotopes 43K, 43Sc, 44mSc, 44gSc and 44Ti were studied by the stacked foil activation technique up to 37 MeV. High-resolution gamma-spectrometry measurements were performed on an HPGe detector in order to determine the activity of the irradiated Sc2O3 pellets and Ti monitor foils. The reaction cross-sections were measured from their respective thresholds up to Ep = 36.4 MeV and were compared with previous values reported in literature. Possible batch yields and optimal irradiation parameters for generator 44Ti -44gSc in high current accelerators are discussed.
