Abstract

Ion mixing of elemental 4d-5d metallic bilayers at 77 K by 600 keV Xe ++ ions has been studied to test the validity of the phenomenological model of ion mixing that predicts a dependence on the chemical heats of mixing, ΔHmix, and on the cohesive energies, ΔHcoh, of the bilayer elements. A series of samples was chosen to minimize the variation in kinematical properties between samples while maximizing the variation in heats of mixing. The experimental results agree well with the model's predictions, and the experimentally determined constants K1=0.034 Å and K2=27 agree with those of previous work.
