Résumé: The spectral line shapes of the absorption and emission are very useful for the diagnosis of temperature and density in plasmas. The profiles of the spectral lines of plasmas are widened asymmetrically around the center of line, and this asymmetry is caused by several effects which as: the fine structure, the quadripolar Stark effect, the very high principal quantum number and the effect of opacity. The aim of this work is the study of asymmetry of the profiles of lines in no optically thin plasmas and the analysis of this asymmetry according to the thickness of the medium and the scattering angle of the radiation
