EXPERIMENTAL STUDY OF Ar-O2 LOW-PRESSURE DISCHARGEVANJA MARGETIĆ and DAMIR VEŽA Institute of Physics, P. O. Box 304, HR-10001 Zagreb, Croatia Received 16 March 1998; Accepted 24 June 1998We report measurements of electron temperature of DC and RF discharge in pure Ar and Ar + 10% O2 gas mixture, and the measurements of collisional broadening by argon of three oxygen lines at 777 nm (3p 5P0,1,2® 3s 5S2 transitions) in an Ar + 10% O2 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. PACS numbers: 32.70.Jz, 33.70.Jg
