Calculation of the spectroscopic characteristics of biatomic van der Waals molecules and ions: Inert gas atom — halogen-type inert gas ion in the ground state

The interatomic potentials in a system formed by an ion of an inert gas in the ground state and an atom of an inert gas (e.g., Ne⁺, Ar⁺-Ne, Ar, Kr, Xe) are calculated on the basis of a calculation of the most important polarization diagrams of perturbation theory in the Thomas-Fermi approximation. The calculation employs the effective pseudopotential method using a new form of the polarization interaction potential. Results are presented from a calculation of the quasimolecular terms of particular van der Waals systems that improve existing data; some of the data were obtained in earlier studies.
