Abstract
The length of a two-dimensional critical nucleus has been measured, and the Gibbs-Thomson formula has been experimentally verified on orthorhombic lys ozyme crystals. The step velocity was found to be independent of its length . The critical length initiating the step motion can be determined by a low density of kinks on a step, and not the critical-nucleus size. The invalid ity of the Gibbs-Thomson formula in this case is discussed. (C) 2001 MAIK " Nauka/Interperiodica".
