Probability Law in Atomic Cluster Production and Its Structure Analysis

The formation of polyolement atomic clusters is found to be controlled by statistics law.Clusters of meeting statistic distributions can be written as AB_n or AB_nC_m, in which A is nucleus of a cluster and B, C are variable units. A set of clusters from same nucleus A and different number of B or C units can be fitted by same lognormal curve. If observing from the position of statistics laws, all AB_n and most AB_nC_m types of clusters are similar with the binary clusters. Some other AB_nC_m type of clusters formed with substitute reaction, i.e. unit B is substituted by unit C in clusters formation, and the size or construction of whole set of AB_nC_m is not changed.
