The relation of T/sub e/ and n/sub e/ to the time factor in deionization of mercury discharge plasma in the pressure range 1 to 58 x 10/sup -3/i mm and at a discharge current of 1.3 amp was studied. The abating laws for n/sub e/ determined by probe measurements and by oscillograms of pure ion current proved to be identical. At initial deionization stages T/sub e/ drops faster with increased pressure. ln the deionization process, the difference T/sub e/ -- T/sub g/ slowly diminishes, but equilibrium was not reached after 400 mu sec. The higher the pressure the lower the finite temperature. Calculations show that inelastic first order shocks play the most important part in electron gas cooling in the initial stages of the process, at all pressures and with p = 1 to 5 x 10/ sup -3/) mm. Elastic losses prevail at later stages of the process when p> 10 x 10/sup -3/ mm. Metastable atoms play an important part in both initial and later stages. (R.V.J.)
