Abstract
Stark widths (W) of 23 doubly ionized oxygen (O III) spectral lines belonging to the ten highest multiplets in the 3s3p and 3p3d transitions have been measuredin the optically thin oxygen plasma created in a linear, low-pressure, pulsed arc discharge at a 42 000 K electron temperature and 1.65 × 1023 m-3 electron density. They are not measured before and four (295.969, 311.567, 312.163 and 313.279 nm) of them in the two multiplets (3p 1P – 3d 1Do and 3p 3S – 3d 3Po) are the first data in this field. In four multiplets (3p 1P – 3d 1Do, 3p 3S – 3d 3Po, 3p 5Do – 3d 5F and 3s 5P – 3p 5So) our W are the first measured data.
