Abstract: Distribution of clusters on particle number and concentration are studied in two-dimensional Lennard–Johnes gas by molecular dynamics method. For selection of cluster in dense matter new geometric and energetic criteria are proposed. The energetic criterion in contrast to criterion proposed before take into account different channels of cluster decay. Also radial distribution function near critical point and dependence of cluster bound energy upon each particle in cluster vs. cluster particle number are culculated.
