Electron beam excitation of rare-gas alkali ionic excimers

The observation of fluorescence from ionic rare-gas alkali molecules excited by an electron beam is reported. Gas mixtures of argon and xenon with hot vapors of either rubidium or cesium were excited to obtain emission from (XeRb)+ at 164 nm and (XeCs)+ at 160 nm. The spectral features observed in (...

Description
Summary:The observation of fluorescence from ionic rare-gas alkali molecules excited by an electron beam is reported. Gas mixtures of argon and xenon with hot vapors of either rubidium or cesium were excited to obtain emission from (XeRb)+ at 164 nm and (XeCs)+ at 160 nm. The spectral features observed in (XeRb)+ are assigned to three upper electronic states.
