The radioisotopes Mn/sup 54/, I/sup 125, and I/sup 130/ were produced at higher rates and at lower cost when targets of isotopically enriched Cr/sup 54/, Te/sup 125/ , and Te/sup 130/ were bombarded with protons in the ORNL 86-inch Cyclotron. The product isotopes were carrier-free and relatively free of undesired radioisotopes. The use of enriched isotopes as cyclotron targets is economically attractive when they can be recovered and reused. To obtain the maximum production rate for radioisotopes in a caclotron, both the usable beam power and the excitation function of the nuclear reaction must be considered. (p,n) reaction production rates were increased by a factor of 1.7 by decreasing the proton energy from 12 to 18 Mev and doubling the output current. Methods of reducing the energy below the maximum design value are discussed. (auth)
