Stark widths of six spectral lines from neutral and multiple ionized boron and three spectral lines from neutral sodium spectra have been measured in a pulsed linear arc plasma. All the measurements have been done in the electron density range of 1.66 × 1023–2.55 × 2023m-3 and in the electron temperature range of 40 000-50 000 K. Some of these experimental values are compared with existing theoretical data.

The Stark width and shift of six Zn Ir and six Cd ii spectral lines have been measured for the electrondensity range of 1.0X10 -1.23X10 m ' and for an electron-temperature range of 23000 -33000 K in a pulsed linear arc plasma discharge in SF6 and argon-helium mixture. Obtained Stark-width data were compared with the values calculated on the basis of various theoretical approaches.

Half-widths of fifteen Stark broadened argon II lines have been measured in argon plasma behind the reflected shock wave produced in an electromagnetically driven "T" tube. The plasma electron density was determined by the laser interferometry at three different wavelengths, while the plasma temperature was measured from relative intensities of A II lines. Temperatures were in the range 8,500--16,500 ~ electron densities varied from 1.82 to 3.94 9 1017 crn 3. The measured AII linewidths are compared with theoretical and other experimental results. It is shown that a) the broadening of AII lines is in good agreement with the theory, b) line broadening increases linearly with electron density, and c) the Stark broadened lines follow the dispersion profile to the distance of at least three halfwidths from the line center.
