Abstract 

Radioisotopes are becoming increasingly important in nuclear medicine in recent times, this is affirmingly connected with their use in nuclear diagnostic procedures, and especially the commonly employed positron emission tomography (PET) and single photon emission computed tomography (SPECT) as well in the therapy of a number of ailments such as cancer. This research aim to provide current cross-section production processes in the theoretical and experimental results of proton induced reaction of iodine isotope on projectile energy range of 1–20 MeV in order to improve the reliability of nuclear stimulation. The excitation functions for the production of 126,127Xe, 123Te and 126I from (p,2n), (p,n),  (p,na) and (p, np) reactions on 127I nucleus respectively, were investigated using EXIFON code. The calculated data were compared with experimental data (EXFOR database) and evaluated nuclear data files (ENDF) and a good agreement was obtained. The calculations were aimed to obtain a threshold for each reaction and the maximum cross-section so that to facilitate production of these radionuclides to prevent a medical crisis in the event of a shortage.
