The radiolytic reaction between graphite and carbon

Abstract The magnitude of the effect of CO on the radiation-induced reaction between CO2 and graphite depends critically on the geometrical arrangement of the system, the temperature and the gas pressure. When the majority of the irradiated gas is in the pores of the graphite the maximum effect occurs below a CO concentration of 0.5%. The absolute G(−C) in the complete absence of CO is
