PRODUCTION OF 61Cu BY α- AND 3He BOMBARDMENTS ON COBALT TARGET

Abstract
For the production of 61Cu for medical use, natural cobalt was bombarded with α or 3He particles up to 40 MeV. The best bombardment conditions were determined on detailed examination of the excitation curves and thick-target yield curves for 61Cu and the by-product nuclides. 6 mCi/μAh of 61Cu could be obtained by bombardment with 40 MeV α particle and separated by anion exchange method with high radiochemical purity in carrier-free state.
