Abstract

Abstract The curves of growth were used in order to determine the Doppler absorption coefficient at the line center, k D0 , from absolutely measured line intensities (equivalent widths) and theoretical widths. It is shown that the relative line intensities from a single path and a double path may be used for the determination of absorption coefficients and absolute oscillator strengths, for estimating absorption at the inhomogeneous ends of a plasma column, and for assessing the approach to thermal equilibrium. Measurements were carried out on the red argon lines arising from the 4 s–4 p transition arrays. The influence of plasma diagnostics on the f-value is considered, and our f-values are compared with other measurements.
