Abstract

The mechanism for the “disappearance” of spectral lines in a nonideal plasma is explained theoretically. A comparison of the calculated results with the experimental data from measurements of the emission spectra from a shocked xenon plasma makes it possible to draw the conclusion that this mechanism is attributed to the Stark broadening of the spectral lines. Quantum-mechanical calculations of the state of an ensemble of plasma atoms and ions were carried out on the basis of the ion plasma model. The parameters of the Stark broadening were calculated using the method developed by N.N. Kalitkin and I.O. Golosno\(\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\smile}$}}{l} \).
