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.
