Sažetak
Abstract. We report measurements of the Stark- shift and Stark-width of sodium spectral lines corresponding to nS-3P and mD-3P transitions. Measurements have been made on AC driven high pressure Na-Hg-Xe and Na-Cd-Xe discharges. Electron density has been determined from the measurements of the Stark-shift of sodium spectral line. The electron temperature and the density of neutral particles have been determined analyzing the shape of the measured sodium atomic lines, by comparison of the calculated and the observed line profiles. Electron density and temperature range from 6×1021 to 1×1022 m-3 and from 3800 to 4100 K, respectively. Dependences of measured Stark- shifts and Stark– widths on electron density and temperature have been investigated. The final results have been compared with available theoretical and experimental data.
