Clusters with Pair Interaction of Atoms

Abstract

The case of a pair interaction between atoms is the simplest case for a system of bound atoms. For such an interaction in a cluster, energetic cluster parameters can be expressed through parameters of the interaction potential of two isolated atoms, that allows one to analyze properties of these clusters in a simple way. In considering such clusters we are guided by clusters of rare gases where the interaction potential between neighboring atoms in a system of bound atoms is small compared to a typical electron energy. Because of a weakness of interaction between rare gas atoms, one can neglect three-body and many-body interactions between atoms. This simplifies the problem and allows one to ascertain the role of shortrange and longrange interactions for properties of a system of many bound atoms.KeywordsCluster AtomMagic NumberFilling LayerSpecific Surface EnergyTotal Binding EnergyThese keywords were added by machine and not by the authors.
