Using the Baranger nonadiabatic impact theory for different interaction potentials the values of pressure broadening and shift parameters for the 326.1 nm Cd line perturbed by Ar and Kr were calculated. Results are compared with both experimental values and those calculated in our previous papers using an adiabatic treatment.

EN
A detailed analysis of the deviations from the Voigt profile caused by the correlation effects and collision-time asymmetry observed by means of a Fabry-P'erot interferometer is presented. An expression for the response of scanning Fabry-P'erot interferometer to the speed-dependent asymmetric Voigt profile is derived.

Profiles of the self-broadened 748.8 nm Ne line emitted from a glow discharge in neon in the pressure range between 0.8 and 100 Tr were measured using an improved experimental setup with pressure-scanned Fabry-Perot interferometer. First, line profiles were analysed using an ordinary Voigt procedure which yielded the Doppler widths decreasing with the increase in neon pressure. Using a speed-dependent Voigt profile it was shown that for the 748.8 nm line the correlation between the Doppler and collisional broadening plays an important role. However, the values of the pressure broadening and shift coefficients determined by the speed-dependent Voigt analysis were found to be only slightly different from those obtained by the ordinary Voigt analysis. A systematic error in the determination of perturber concentration in our previous investigation was corrected.
