Activation cross-sections of 3He-particle induced nuclear reactions on natural silver up to 27 MeV

This study presents new experimental cross-section data for the production of radionuclides ¹⁰⁴ᵐ, ^104g, ¹⁰⁵ᵐ, ¹⁰⁶ᵐ, ¹¹⁰ᵐAg, ^107g, ¹⁰⁸ᵐ, ^108g, ¹⁰⁹, ¹¹⁰ᵐ, ^110g, ¹¹¹In, and ¹⁰⁷, ¹⁰⁹Cd produced via ³He-particle irradiation of natural silver using the stacked-foil activation technique. The results were validated by comparison with previous studies, corrected for updated γ-ray emissions, if possible. Beam energy and current were verified using the monitor reactions, which improved data reliability. The experimental excitation functions were further compared with theoretical predictions from the EMPIRE code and the TENDL-2023 library, revealing notable discrepancies that underscore the need for refinement in nuclear reaction models for ³He projectiles. Thick target yields were also calculated, with ¹⁰⁷ᵍIn and ¹⁰⁸ᵐIn showing the highest production rates. The yields are generally insufficient for large-scale radionuclide production. These results anyhow extend the existing experimental database for ³He-induced nuclear reactions, contribute new material for the advancement of nuclear reaction modeling, as well as for applications in activation analysis and astrophysics.
