ABSTRACT: 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.
