Abstract
Three elementary displacement steps of tungsten diatomic cluster migration on the W {110} plane have been identified. The relative frequencies of observing these displacement steps out of 597 observations at 299 ± 5 K are given. Several possible migration mechanisms which involve uncorrelated individual atomic jumps and which can qualitatively account for the three observed elementary cluster displacement steps are also discussed.Keywords
