Stark widths of 32 OII spectral lines have been
measured, for the first time in 16 cases to the authors' knowledge.
A pulsed arc was used as a plasma source. The electron
density, determined both interferometrically and spectroscopically,
covers the range .
The electron temperature, determined from Boltzmann-plots,
covers the range of 25000-47000 K. Possible dependencies of
Stark width on the temperature have been checked. The measured
widths are compared both with theoretical and
experimental data available in the literature.
