Abstract : The rates of formation of deuterium oxide in Co60 gammairradiated gaseous mixtures of deuterium and oxygen have been examined at initial deuterium concentrations, (D2)o, ranging from 0.00037 to 0.0037 mole/l. First- and zeroorder reaction rates with respect to deuterium were observed for the low and high (D2)o, respectively. The corresponding rate constants found were 0.0053/hr and 0.0000045 mole/l hr at a dose rate of 5.61 x 10 to the 16th power ev/cc hr. The initial G values for deuterium oxide formation, G(D2O), for the low and high (D2)o were 2.9 and 7.3, respectively. A search for reaction products other than deuterium oxide, using ferrous sulfate and titanium sulfate reagents, established that (a) no deuterium peroxide was formed as a stable reaction product and (b) a wallstabilized species, whose identity was not extablished, was observed; it oxidized the ferrous sulfate reagent but did not react with the titanium sulfate reagent. An 8-fold change in the surface-to-volume ratio of the irradiation vessel did not significantly affect the concentration of this species. (Author)
