On the parametric description of an inhomogeneous, optically dense plasma

Abstract

The source inhomogeneity parameter is calculated for various distributions of excited atoms and variations of the line width along the discharge cross section, for a “purely” dispersive shape of the spectral line.

The frequency dependence of the inhomogeneity parameter, which varies with increase of the radial dependence of the line width, is determined. It is shown to be necessary to take this fact into account in calculating the shape of a self-reversed line.
