Abstract
The three‐body heterogeneous and wall recombination coefficients for atomic oxygen were measured using an electron paramagnetic resonance spectrometer to monitor the time dependence of the atomic oxygen concentration. This measurements was made for a pressure range from 0.224 to 1.10 torr using pyrolysis of ozone as a source of oxygen atoms. The three‐body heterogeneous rate constant (with molecular oxygen as the third body), resulting from a computer fit of the data to the usual recombination model, was determined independent of ozone concentration to be (6.26±0.94) ×10−34 cc2 molecule −2 sec−1. The wall recombination efficiency γ for a fused metaphosphoric acid–sodium metaphosphate mixture (the wall coating) was found to be 9.1×10−6.
