The heterogeneous reactions of H atoms and CH3 radicals with a polycrystalline diamond surface have been studied using discharge flow and pulsed excimer-laser photolysis techniques coupled with photoionization mass spectrometry. A random walk Monte Carlo solution of the three-dimensional diffusion equation was used to interpret the experimental data and to obtain the collisional efficiency for removal of hydrogen atoms by the diamond surface (γw) over the temperature range 300-1119 K. The result expressed in Arrhenius form is γw(H on diamond)=10-3.4±0.3+100.29±0.15 exp(-(6020±470)cal/RQ).
