Measurement of Stark widths in single ionized oxygen

Stark widths of 32 OII spectral lines have been measured, for the first tim e in 16 cases to the authors' knowledge. A pulsed are was used as a plasma source. The electron density, determined both interferometrically and spect roscopically, covers the range (2.5-7.5)10(22) m(-3) The electron temperatu re, determined from Boltzmann-plots, covers the range of 25000 - 47000 K. P ossible dependencies of Stark width on the temperature have been checked. T he measured widths are compared both with theoretical and experimental data available in the literature.
