VUV Spectroscopy of Rare-Gas Van Der Waals Dimers

  • Chapter
Photophysics and Photochemistry in the Vacuum Ultraviolet

Part of the book series: NATO ASI Series ((ASIC,volume 142))

Abstract

It is well known that ground-state rare-gas atoms repel each other, except for van der Waals forces which lead to weak molecular binding in all of the homonuclear and heteronuclear dimers except, possibly, He2 [1]. Removal of the outermost electron, which is anti bonding in character, leads to a stable ground ionic state for all of the dimers. Several of the excited ionic states are bound as well although, in general, the dissociation energies of the excited states are much smaller than that of the ground state. The addition of an electron in a Rydberg orbital to an ion in one of the bound states may result in a bound Rydberg state; however, little is known about the stable excited states of the neutral rare-gas dimers, except for those molecular states which arise from the lowest atomic resonance states (i.e., the molecular excimer states). A notable exception is the detailed multichannel quantum defect theory analysis of the Rydberg states in He2 presented recently by Ginter and Ginter [2].
