Abstract

Optical absorption spectroscopy has been applied to measure the abs. population densities of the first excited states levels of at. hydrogen H*(n = 2) and argon Ar*(4s) in an expanding cascaded arc plasma in a hydrogen-argon mixt. It is demonstrated that the method allows us to det. both H*(n = 2) and Ar*(4s) abs. d. radial profiles for H2 admixts. in Ar ranging from 0.7 to 10% with good accuracy. It has been shown that the d. of hydrogen excited atoms H*(n = 2) serves as an indicator of the presence of argon ions and hydrogen mols. in the expanding plasma. A kinetic model is used to understand evolution of H*(n = 2) d. in the expansion, and to est. the total at. hydrogen population d. and hydrogen dissocn. degree in sub- and supersonic regions of the plasma.
