From the analysis of the time decay of VUV lines intensities at 82.4 and 109.1 nm corresponding to radiation transitions from Rb (4p5s5p 4S3/2) and Cs (5p6s5d 4P5/2) quasimetastable autoionization levels the rates of the charge transfer reactions of the metastable rubidium and cesium ions on their atoms were measured in mixtures of He-Rb and He-Cs. They were found to be equal to α (Rb) = 3,76(± 0,6)×10–11 см3/с and α (Cs) = 9,94(± 1,5)×10–11 см3/с, respectively.
