Vacuum ultraviolet luminescence of molecular xenon in Xe/Kr and Xe/Ar mixtures excited by a fast-electron beam

The effects of inert gases on the intensity of vacuum ultraviolet luminescence of molecular metastable Xe has been studied experimentally under excitation by an electron beam of 300 keV. The range of gas pressure in the experiments was 10,000-600,000 Pa for the xenon, and 10,000-900,000 Pa for the gas mixtures. It is shown that the introduction of the gas mixtures slows down the damping of UV radiation. It is shown that the introduction of impurities into xenon gas can lead to the formation of heteroatomic excited molecules. A theoretical model of the kinetics of pulse decay processes in xenon is proposed on the basis of the experimental results.
