Scaling method in atomic and molecular physics

Joint Institute for High Temperatures, Russian Academy of Sciences, ul. Izhorskaya 13/19, Moscow, 127412, Russian Federation

The scaling method based on the parameters of pair atomic interaction potentials proved to be suitable for analyzing the various parameters of dense and condensed rare gases Ne, Ar, Kr, Xe and accurate to within a few percent. In this paper, the interaction potential between radon atoms is evaluated based on the relevant scaling laws and using the macroscopic quantities determining the behavior of dense and condensed gases. Properties of systems of bound particles with a specific pair interaction potential between them are considered, leading to the conclusion that the long-range interatomic interaction is of no significance as far as the properties of dense and condensed rare gases are concerned. Phase transitions in clusters and atomic systems at high pressures are analyzed, and some aspects of scale invariance in dense and condensed molecular systems are under discussion.
