Calculation of spectroscopic parameters of diatomic van der waals molecules and ions: inert-gas atom-inert gas ion of the halogen-type in the ground state

Based on the effective-pneudopotential method with the use of a new form of the polarization-interaction potential, obtained on the basis of calculating the most important polarization diagrams of the perturbation theory in the Thomas—Fermi approximation, the authors calculated interatomic potentials in the inert-gas ion in the ground state-inert-gas atom system: Ne⁺, Kr⁺−Ne, Ar, Kr, Xe. The results of calculating on its basis quasi-molecular terms of the sought van der Waals systems that refine the available data are given; a part of the results is obtained for the first time.
