“…There are two main ways to produce a 123I: The first is the direct method as shown in Equation (1), while the second is through the production of 123Xe, which in turn is left to decompose to 123I shown in Equation (2). The second method has the advantage of easily separating the xenon from the original target material and allowing it to decay separately, giving I-123 very little contamination from other radioactive isotopes of iodine [4]…”

123I is the most widely used cyclotron-produced radio-halogen in medical research. In this paper, excitation function formulae for the nuclear reactions of 123I production are introduced. 124Te (p, 2n)123I and 127I (p, 5n)123Xe → 123I nuclear reactions have been studied as a function of the energy of the neutrons. Both two formulae were created using the least squares regression of the experimental cross sections data, which were obtained from the Experimental Nuclear Reaction Data EXFOR Database version of 2023. The proposed formulae were evaluated using two statistical indicators for goodness-of-fit. High agreement was observed between the empirical and experimental results for both nuclear processes.
