    Abstract

    Experimental results of spectroscopic measurement of spontaneous emission from argon gas excited electrically in a nozzle discharge followed by supersonic expansion are described. A strong line emission at 152.6 nm originating from Si(II) 4s-3p is observed together with relatively weak emission line around 126 nm. A theoretical model that takes account of collisional gas kinetics, discharge processes, and empirical treatment of the free jet expansion is developed to examine the capability of the discharge excited gas as a laser medium for Ar2 excimer at 126 nm wavelength.
