~(48)V is a medical radionuclide applicable for positron emission tomography (PET). It can be produced through α-particle-induced reactions on ~(45)Sc. In this study, we measured the cross sections of these reactions using the stacked-foil activation technique and γ-ray spectrometry. The measured cross sections up to 29 MeV are in good agreement with data above 22 MeV obtained in our previous study. We also calculated the physical thick target yields based on the measured cross sections. The results suggest that a projectile energy of approximately 15 MeV is optimal for achieving nearly saturated ~(48)V production while minimizing the formation of radioactive co-products.
