Measurement of Terbium Isotopes Yield in Irradiation of Eu-151 Targets by He-3 Nuclei

摘要

This article is devoted to obtaining the alpha-emitter Tb-149 for radioimmunotherapy. A method for producing Tb-149 based on the reaction Eu-151(He-3, 5n)Tb-149 is proposed. It is proposed that europium with native isotopic composition (Eu-151 - 47.81%, Eu-153 - 52.19%) or enriched Eu-151 be used as the target. The 29 MeV threshold of the indicated reaction makes it possible to use accelerators with the initial He-3 energy 40-70 MeV.
