Recombination Reactions of 5-eV O(3P) Atoms on a MgF2 Surface

摘要

A source of hyperthermal, ground-state, impurity-free, atomic oxygen of an energyvariable in the range 2-100 eV has been developed. Experimental results are presented of emission spectra in the wavelength range 250-850 nm produced by collisions of 5-eV O(3P) atoms with adsorbed NO and CO molecules on a MgF2 surface. The emission with adsorbed CO is due to the B to X transition in CO2, while that with NO is consistent with the continuum B to X and A to X emissions in NO2.
