Abstract

A method for the production of ⁵⁷Co (271.65) for medical applications using metallic ⁵⁹Co as a target, and the ⁵⁹Co(p,3n)⁵⁷Ni→⁵⁷Co reaction was explored. Excitation functions for proton-induced reactions in the 40- to 10-MeV energy region, as well as thick-target and cumulative yields for the directly-produced ⁵⁷Ni (35.99h) and indirectly-produced ⁵⁷Co were also measured and then compared to previously reported values. A radiochemical purification procedure based on anion-exchange chemistry is also reported. ⁵⁷Co with >99.9% radionuclidic purity was obtained. The indirectly-produced ⁵⁷Co yield in the 40- to 24-MeV energy region was measured as 2μCi/μAh.
