Nuclear cross-section measurement of terbium-155 production using reactions : induced by light ions on Eu, Gd, Tb and Dy targets

This study explores different production pathways for 155Tb, an emerging radionuclide for theranostic applications in nuclear medicine. Excitation functions were measured using various targets and irradiation methods, revealing promising routes, particularly indirect production using protons on 159Tb and α particles on natGd. Direct production on enriched 153Eu using α particles also shows potential. These findings offer insights into optimizing production processes in terms of yield and purity, enhancing accessibility to 155Tb for clinical applicatons, and advancing theranostic radiopharmaceutical research.
