Abstract : The effect of various diluent gases on the rate of the self-induced exchange between tritium and water vapor was investigated. The gases studied were: helium, neon, argon, krypton, xenon, air, nitrogen, oxygen, hydrogen, and ammonia. The average value found for a second-order rate constant, for inert gases agreed with that found previously (See AD-246 259). Air and nitrogen as diluents yielded rate constants of 0.00127 and 0.00086 ml/mc/hr, respectively. Oxygen increased the rate over that observed in air, and hydrogen and ammonia both were found to decrease it sharply. (Author)
