Scandium (Sc) radioisotopes have been attracting increasing attention in medical applications. 47Sc, which has the potential for targeted radiotherapy, is quite promising as a candidate for theranostic pairing with the β+-emitting radioisotope 43Sc or 44gSc. The excitation functions for producing 43,44m,44g,46,47Sc through (α,x) reactions on natural calcium (Ca) up to an energy of 25 MeV were experimentally measured and critically compared with previous experimental reports and theoretical data obtained by EMPIRE-3.2.3 code and from TENDL-2021 library. The physical yields for producing of 43,44m,44g,46,47Sc through (α,x) reactions on natCa were determined using the measured production cross-section of the radionuclides and the stopping powers.
