LINE-SHAPES OF MULTIPLY-CHARGED IONS - ION DYNAMICS AND CONCENTRATIONEFFECTS

The model microfield method has been applied to the broadening of spec tral lines emitted by multiply charged hydrogenic ions in pure and bin ary mixtures. Special attention is paid to the calculation of the ioni c microfield distribution function. Extensive comparison with other th eoretical results are performed. Fine structure effects are shortly di scussed. This paper confirms the importance of ion dynamics effects in the line shapes and discusses in detail, in the case of mixture, the dependence of the profile on the concentration of the radiating specie s.
