Rare Gas Clusters Containing Charged Atoms

摘要

Three kinds of rare gas (R) containing clusters are considered in this article:(I) ionic clusters Rn+ and (R M)+, M being another atom or a molecule, (II) neutral rare gas-halogen n n clusters R n X with R X electron transfer, and (III) Rydberg excited R n clusters. These clusters have much in common, as all of them contain ions or ionic cores, with the positive charge delocalized mostly between some number of atoms. Such systems can be treated by the semiempirical diatomics-in-ionic-systems (DIIS) method. We present in this article a brief description of the DIIS method and the results of its applications to the kinds of clusters mentioned above. The article presents also discussions of results obtained by other theoretical methods and experimental studies.
