Study on (<i>p</i>, <i>n</i>) reactions for the production of iodine isotopes used in nuclear medicine at 1–20MeV protons

The study illustrates how to calculate (p, n) reaction cross-sections for iodine isotopes using the EMPIRE 3.2.3, ALICE-ASH, and TALYS 1.95 computer programs, along with a developed empirical formula. The excitation functions of [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I, [Formula: see text]Te(p, [Formula: see text]I and [Formula: see text]Te(p, [Formula: see text]I reactions were calculated at incident proton energy ranges of 1–20[Formula: see text]MeV. The previous calculated data from the evaluated data based on the Evaluated Nuclear Data File (ENDF), such as TENDL-2019, TENDL-2021, MENDL-2, IAEA-Medical and IAEA-Therapeutic, as well as the experimental nuclear reaction cross-section data (EXFOR) about the above reactions, have been collected. The empirical formulas have been compared with computer codes and the experimental and evaluated data found in the EXFOR and ENDF. In general, the calculated, evaluated and experimental ([Formula: see text]) reaction cross-sections are in good agreement.
