Excitation functions were measured using the stacked foil irradiation technique from threshold energies to 28 MeV for (3)He- and to 21 MeV for alpha-particle induced nuclear reactions on natural antimony leading to the formation of (121,123,124)I radioisotopes. The measured excitation functions were compared with the contradicting results of the earlier investigations found in the literature and with the curves predicted by the ALICE-IPPE and EMPIRE-II codes. Integral yields were also calculated and compared with the experimental thick target yields reported in the literature.
