Thick-target production rates of 55Fe produced in the proton bombardment of Mn, Co and Ni were investigated from threshold up to 100 MeV. Impurity levels of the only radiocontaminant of importance, 59Fe, were also considered. It is shown that the optimum production rate at energies above ∼ 35 MeV will be achieved by utilizing a tandem Mn/Ni target. Theoretical calculations performed with the computer code ALICE/85/300 were found to be in good agreement with the measured 55Fe thick-target production-rate curves.
