Paper Abstract

Alkali rare gas triatomic ionic excimers have been observed for the first time. These molecules have been produced by electron beam excitation of rare gas alkali mixtures at high pressure and high temperature. Emission spectra centered at approximately 159 nm have been observed and attributed to Kr2+Cs ions. Lifetimes and binding energies of the lowest excited states have been estimated. Simple kinetic considerations allowed us to propose two formation processes of these ions and to estimate their rate constant.
