Study of the parameters of the He(3 3S)-He(2 3P) line

Abstract : We have observed emission spectrum in dense plasmas of helium excited by a corona discharge at 706.69 nm. In continuation of an analysis of spectra obtained in gaseous helium at 300 K, we report on a study of the line parameters of the observed spectra. We discuss the major importance of temperature and perturber density in the broadening, shift and asymmetry measured from calculated profiles within a unified line shape semi-classical theory. The comparison is done with existing data derived from experimental spectra at 300 K. The theoretical work is extended at lower temperatures down to 40 K.
