Abstract
The novel experimental approach is applied to investigate the cross sections for rotational relaxation [MATH] in the SF6-Ar mixtures irradiated by pulsed CO2 laser line. The applied method is the pulsed photoacoustic technique, and it is based on proposal for [MATH] determination by transmission spectroscopy technique. The collisional effects have been investigated for the 0,l-0,8 J/cm2 laser fluence range. Also, the collisional effects on rotational and translational temperature (TR) for SF6-Ar mixtures have been calculated.
