Description

The adsorption of the heavy actinoids Cf, Es, Fm, and Md on polycrystalline titanium and molybdenum has been studied by thermochromatography in comparison with several well-known metallic elements, in trace amounts. The data lead us to suggest that Es, Fm, and Md are divalent in the metallic state and, moreover, that the position of their f energy levels relativg to the Fermi-energy is lower than in the cases of Cf and Yb. A correlation was found between the experimental enthalpies of adsorption of the heavy actinoids and their predicted enthalpies of sublimation
