Experimental study of Ar-O2 low-pressure discharge

We report measurements of electron temperature of DC and RF discharge in pure Ar and Ar + 10% O$_{;2};$ gas mixture, and the measurements of collisional broadening by argon of three oxygen lines at 777 nm (3p $^{;5};$P$%_{;0, 1, 2};$ $ ightarrow $ 3s $^{;5};$S$_{;2};$ transitions) in an Ar + 10% O$%_{;2}; $ gas mixture. The electron temperature is determined using the double probe technique and the logarithmic plot method. The line widths of oxygen atomic lines broadened by argon were measured with the high-resolution monochromator and later analyzed numerically.
