Relative radial concentration profiles of atomic hydrogen in an atmospheric-pressure argon-hydrogen free-burning 200 A arc discharge were measured using laser-induced fluorescence by 2-photon excitation of the ground state of atomic hydrogen. Radial profiles are presented for three axial locations. A comparison between the measured profiles and profiles calculated using a diffusion model that considers demixing processes is made, indicating that local chemical equilibrium is not maintained at larger radii in the arc.
