Abstract

UV emissions of Ne-Xe-Cs mixtures excited by a pulsed electrical discharge were investigated experimentally as a function of gas pressure and gas composition. For the studied discharge plasmas no fluorescence emissions originating to the radiative decay of the ionic excimer molecule (XeCs)⁺ at 160 nm were observed. Discharge excitation seems to be unsuitable for the generation of this ionic excimer. Previously reported fluorescence emissions due to the radiative transitions in the discharge-excited (XeCs)⁺ molecule could not be confirmed in our experimental conditions. An upper Limit for the unknown rate constant of the formation reaction Xe*+Cs⁺+Ne→Xe⁺Cs+Ne was given
