A statistical distribution model was summarized for the cluster ions generated from laser vaporization. In this paper, a distribution function has been deduced for the laser generated cluster ions. To deduce the equation, kinetic equations were presented for the cluster ions based on ion-molecular reactions, the Smoluchowski equation was extended to described the reaction, and an irreversible aggregation process was assumed in which all charged and neutral cluster species have equal aggregation rate constant. Distribution of the deduced equation is shown to agree very well with the statistical size distribution of cluster ions observed in experiments.
