Abstract

Two-photon absorption laser induced fluorescence (TALIF) is applied to measure the recombination coefficient of atomic oxygen under several kPa pressure.ァThe recombination coefficient of oxygen on the oxide SiC is estimated as 6.4×10^-3 at the total pressure of 2,240 Pa, the surface temperature of 1,150K. From this result, we confirm that the recombination coefficient has pressure dependency.
