Abstract:

The refractive index was measured at wavelengths of 6328A and 1.15 microns in an argon plasma produced by a D.C. electric arc. The refractive index was correlated with temperatures determined from atomic line and continuum emission coefficient measurements. The experimental results were compared with simple dispersion theory which considers contributions from ground state atoms and free electrons. Author
