Abstract

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