ABS>The products of the Szilard-Chalmers reaction in ferrocene were separated by solvent extraction and chromatography. For samples irradiated in the center of the Brookhaven Reactor about 12% of the Fe/sup 59/ activity is found in the form of the parent compound. The yield is increased to about 21% by heating the irradiated samples. The yield of inorganic radioactive iron is decreased by thermally annealing the irradiated crystals; this effect appears to depend on the fast-neutron dose received by the sample during activation. The distribution of radioactive products is not altered by exposing the sample to large doses of gamma -radiation after activation in the reactor. An explanation of the results is offered, which suggests that the following types of fragments are formed in the crystals during pileirradiation: free iron atoms or ions and ironmonocyclopentadienyl radicals as primary disruption products in the (n, gamma ) processes; free cyclopentadienyl radicals, C/sub 5/H/sub 5/; and organic radicals formed by rupture of the C/sub 5/H/sub 5/ rings in ferrocene when fast neutrons are present.
