Electron quenching of KrF* and ArF*

Abstract
The collisional deactivation by electrons of the upper laser levels of KrF* and ArF* has been measured. The rare‐gas/fluorine binary mixtures were excited by a beam of fast electrons. These electron beam pulses were long enough to allow the use of a steady‐state analysis of the fluorescence. Quenching rate constants near 2×10−7 cm3/sec have been obtained.
