Alpha beam monitoring via natCu + alpha processes in the energy range from 40 to 60 MeV

Abstract

Excitation functions were measured using the stacked-foil method for alpha particle-induced nuclear reactions on natural copper leading to the formation of 61Cu, 66Ga and 67Ga in the energy range from 16 to 60 MeV. Extending the recommended database of the nat Cu( α, x) 66 Ga and nat Cu( α, x) 67 Ga processes with our new values, now the above processes can be used for alpha beam energy and intensity monitoring up to 60 MeV. On the basis of the present study it was found that the nat Cu( α, x) 61 Cu process is also a useful candidate for monitor purposes in the 40–60 MeV energy region.
