Abstract
Total Stark profiles of the C II 2993 Å line of a plasma jet of a slit discharge with an evaporating wall. In the interval of electron densities of 1017 to 6 × 1017 cm−3, the electron impact width, the ionic broadening and the shift of the intensity maximum of the line are measured. It is found that, at an inversely quadratic dependence of the electron impact width on the electron concentration, the Stark shift and the ionic contribution to the total width of the profile are linear. It is noted that calculated values of the shift regularly exceed measured values, while the signs of the measured and calculated shifts coincide. The method of approximating experimental data is proposed, which takes into account the interrelation of the main Stark parameters in plasma with a strong interparticle interactions.
