Abstract
The electromigration and thermomigration of light interstitials, such as hydrogen in metals, have been examined in terms of the quantum theory of diffusion of Flynn and Stoneham. The pronounced isotope effect observed in the effective charge Z* is shown to come from the differences in the self trapping distortions of the various isotopes. The qualitative dependence of Z* on isotope, host lattice and temperature are correctly predicted. The interstitial contribution to the reduced heat of transport Q* is calculated directly from the quantum theory.
