Abstract We have studied the feasibility of producing57Co (271.3 d) via the55Mn(α, 2n)57Co reaction (55Mn−100%). The thick target yield of57Co in the 28 to 18 MeV energy region was measured as 3.87 μCi/μAh. However, the proximity and overlap of the excitation functions for (α, n), (α, 2n) and (α, 3n) reactions on55Mn are such that the production of pure57Co in high yields free of58Co (70.8 d) and56Co (78.8 d) has not been feasible. We have also studied a new method for ancillary production of57Co via the reactions58Ni(α, αp)57Co and $$^{58} Ni(\alpha ,\alpha n)^{57} Ni\xrightarrow{{36{\mathbf{ }}h}}^{57} Co$$ during the course of producing62Zn by60Ni(α, 2n)62Zn reaction. In this case the yield of57Co of reasonable purity has been up to 1 μCi/μAh.
