Static systems comprised of degassed anatase and oxygen at initial pressures ranging from 38 to 610 μ were irradiated with cobalt-60 γ-rays and the pressure was measured simultaneously. A distinct increase in the rate of chemisorption at the commencement of irradiation was observed; after prolonged irradiation a nearly steady-state pressure was reached. The data were found to fit an Elovich-type rate equation, with the parameters showing reasonable behavior with variation in the initil pressure. The effect was found to be sensitive to the temperature used for degassing the anatase and to the run temperature. The observed effect did not seem to be related to factors which altered the rate of diffusion.
