ABSTRACT Spatial correlations of most mobile or immobile particles in supercooled SiO[SUB]2[/SUB] model at the temperatures of 2100 K have been investigated using molecular dynamics (MD) method. We evaluate the non-Gaussian parameter for the self-part of the van Hove correlation function, cluster-size distributions and spatial connectivity of most mobile or immobile particles in the model. We have found that mean cluster size grows with decreasing temperature. The mean number of neighbors of fast or slow particles compared with the mean ones has been calculated.
