Abstract

Metastable 117mSn is a promising theranostic radionuclide, suitable for SPECT diagnostic imaging and conversion electron therapy. Its production is based mainly on nuclear reactors, but there is increasing interest in alternative routes with cyclotrons. Theoretical studies are essential to identify the irradiation parameters and conditions to maximize its production, while minimizing the impact of the contaminants. The goal of this study is to investigate the production of 117mSn with a 30 MeV α beam on natCd and natIn targets, as provided by the HIL-UW (Heavy Ion Laboratory - University of Warsaw) U-200P cyclotron. We performed a theoretical analysis of cross section, yield and purity by means of two nuclear reaction codes: Talys (v.1.9), based on a combination of models, and Fluka (v.2018.2.dev), based on Monte Carlo simulations. We compared the theoretical calculations with both experimental data already known in the literature and preliminary results obtained at HIL. A statistical treatment of the models suggests a comparable production of 117mSn for both targets, but a higher radionuclidic purity was found in the case of the natIn target.
