Abstract
Proton-induced reactions on enriched 118Sn up to 18 MeV have been investigated. Using the stacked-foil activation technique, the excitation functions of the reactions 118Sn(p,n)118Sb, 118Sn(p,2n)117Sb, 118Sn(p,α)115mIn, and 118Sn(p,x)117mSn were measured. The available experimental data show good agreement with our measurements. The cross sections for the 118Sn(p,x)117mSn and 118Sn(p,α)115mIn reactions are reported for the first time. The measured cross sections were compared not only with previously published experimental results, but also with theoretical predictions from the TENDL-2023 (TALYS-based evaluated nuclear data library), TENDL-2025 and JENDL-5 (Japanese Evaluated Nuclear Data Library) libraries. Discrepancies between experimental and theoretical data were observed for reactions involving composite-particle emission, such as alpha particles and deuterons. These differences suggest that while current models adequately describe simple two-nucleon emission channels, further refinements are needed, particularly for modeling composite-particle emission at lower proton energies.
