Cross sections for production of 43Sc, 44Sc, and 46Sc isotopes in the 45Sc + 3He reaction
Result description
Reactions 45Sc(3He, ?n)43Sc, 45Sc(3He, ?)44Sc, and 45Sc(3He, 2p)46Sc, resulting from the irradiation of scandium targets with a beam of 3He ions with energy from 5 to 24 MeV, are investigated in experiments on the U120M cyclotron of the Nuclear Physics Institute (Rez, Czech Republic). The activation technique is used to find the yield of the produced Sc isotopes. The induced ? activity in the targets is measured using a high-resolution HPGe detector. Despite the low binding energy of 3He and positive reaction Q values, which leads to formation of the 44Sc and 46Sc isotopes, the behavior of the excitation functions for the formation of these isotopes differs from the behavior of the excitation function for deuterons. Scandium-44 formation cross sectionsreach their maximum at the reaction Coulomb barrier. This is because not only 44Sc but also a stable 4He nucleus is formed in the reaction.
