Reactions of Cobalt with Protons at 60, 100, 170, and 240 Mev

Absolute cross sections are reported for the production of the nuclides Co⁵⁸, Co⁵⁶, Co⁵⁵, Fe⁵², Mn⁵⁶, Mn⁵², Mn⁵¹, Cl³⁹, and Cl38,34 from bombardment of Co⁵⁹ with protons of energies 60, 100, 170, and 240 Mev. The yields appear to be accounted for at the lower energies by a combination of compound nucleus model, knock-on cascade model and for the production of chlorine isotopes a fission mechanism. A knock-on cascade model together with a fission mechanism may be used to explain the yields at the higher energies.
