Abstract
A fully dynamic model of interstitial diffusion in W yields an energy of activation in good agreement with the static relaxation method. However, random-walk statistics are inapplicable except for large diffusion distances; correlation effects are strong and clearly temperature dependent. The latter observations are reconciled with the spatial configuration of the static potential to give a self-consistent explanation.Keywords
