Abstract
Half-widths of several chlorine II lines have been measured behind the reflected shock wave produced in an electromagnetically driven 'T' tube operated in dichlorodifluoromethane. The electron density (2.64-4.27*1017 cm-3) was determined by laser interferometry at two different wavelengths while the electron temperature (13 300-17 800 K) was measured from relative intensities of Cl II lines. Measured Cl II linewidths compare fairly well with the theory of Griem. Some difficulties in computing linewidths are underlined.Keywords
