Abstract
Within a classical macroscopic picture the stability of a super-saturated vapor is a consequence of the surface related activation barrier associated with the growth of small clusters. As indicated in Fig. 1 the free energy change for the formation of small clusters from a vapor is positive and increases with cluster size until a “critical” cluster size is attained. Beyond the critical cluster size subsequent cluster growth results in a decrease in the free energy and the process occurs spontaneously. Because the growth up to the critical cluster size is responsible for the stability of the supersaturated vapor, it is important that it be well understood.
