Calculation of the Excitation Functions of Alpha-Induced Reaction for the Production of 123,124I from Threshold to 40 Mev

Abstract

EXIFON 2.0 code has been used to calculate the (?,n) and (?,2n) reactions of ¹²²Sb for the cyclotron production of ^123,124I which have application in positron emission tomography imaging. For both reactions, the threshold for the reaction obtained from the evaluation compared well with measured values. Results obtained shows good agreement with measurements from EXFOR. It was observed that there is a need for optical model contribution to the pre-equilibrium mechanism of EXIFON at 16MeV for (?,2n) and 27MeV for (?,n) reactions. However, the results show good agreement with available measured data at lower energy level.
