On the role of ion dynamics in the stark broadening of hydrogen lines
ABSTRACT A review and critical discussion of previous treatments of ion dynamics in hydrogen-line broadening by plasmas is followed by the description of a computer simulation of ion motion for the Lyman-β line of hydrogen. The profile of Ly-β is calculated for the static ion case as well as for three dynamic emitter-perturber couples, namely H-H+, H-Ar+, and D-Ar+. Our results, which show an important effect due to ion dynamics, are compared with a recent experimental result and with theoretical results obtained by the model microfield method.

ABSTRACT: The present review is devoted to the current status of microfield notion that was so successful and profitable for experimental and theoretical studies of plasma in gas discharges and thermonuclear modeling installations for many decades. The physical aspects and ideas of the main generally used microfield models are described and analyzed in detail. The review highlights the remaining vague and unclear questions in the subject.International Journal of Spectroscopy. 01/2010;
