The authors investigate the vacuum UV radiation spectra of atoms and ions of Rb, Cs, He, Ne, and Ar in a discharge plasma of their mixtures at different concentration of metal vapors in rare gases. The reactions leading to population and deactivation of resonant states of rare-gas atoms were studied. The observation of lines 109.1, 119.6, and 124.7 nm, corresponding to the radiation transitions from the 5p{sup 5}5d6s{sup 4}P{sub 5/2} quasi-metastable autoionizing level of cesium, allowed the authors to estimate experimentally the cross section {sigma} = (9 {+-} 3) {center_dot} 10{sup {minus}15} cm{sup 2} of the charge-exchange reaction of the metastable cesium ion on the cesium atom, giving as a result the above-mentioned quasi-metastable state of cesium.
