High-spin isomers production in (α,n)-reactions

Abstract

Abstract Results of the studies of the relative yield of high-spin and low-spin isomers in reactions 112Sn(α,n)115Te and 134Ba(α,n)137Ce in the energy range of the α-particles 15 – 31 MeV based on off-beam measurements of induced activity of members of the isomeric pair are presented. Extremely large relative yield for the first reaction is obtained. The features of the second one, which are promising for its use in fundamental studies, are revealed.
