Application of the Smoluchowski equation to the formation kinetics of cluster ions

Cluster ions with various sizes and compositions have been generated from direct laser vaporization. The Smoluchowski rate equation is extended to describe the formation kinetics of the cluster ions, which have been assumed to be produced from ion-molecule reactions with same-rate constants. By solving the kinetic equation analytically we obtained the distribution function of the cluster ions. Analysis of the distribution function showed that the function can characterize the statistical size distribution of the cluster ions and can be reduced to the asymptotic solution suggested by Jullien .
