Abstract

Following our discovery of a new surface state near the facet edges of 4He crystals, it was argued that thermally excited dislocation loops could destroy the facet flatness. Recent measurements of facet profiles of very small 4He crystals indicate that the activation energy of these loops would have to be more than 20 K, which is quite high. The possible consequences of this result are discussed.
