Abstract

Changes in the isotopic composition of electrolyte lithium are studied experimentally when thin-film titanium-aluminum systems are enriched in hydrogen. Strong deviations of the lithium isotope concentration from their natural abundances are observed both in the surface titanium layer and at the titanium-aluminum interface. Analysis of the experimental results permits us to conclude that isotope-induced transformations occur in materials enriched in hydrogen due to cold diffusion of impurity atoms stimulated by hydrogen migration and non-equilibrium chemical reactions.
