Laser-induced fluorescence study of the influence of N $\scriptstyle \mathsf {}$ 2 and CH $\scriptstyle \mathsf {}$ 4 on the $\scriptstyle \mathsf {}$

Abstract

Using a laser-induced fluorescence method a detailed analysis of profiles of the 114Cd 326.1 nm line perturbed by N2 and CH4 was performed which revealed deviations from the ordinary Voigt profile. These deviations are shown to be consistent with fits of experimental profiles to an asymmetric Voigt profile. Coefficients of the pressure broadening, shift and collision-time asymmetry are determined and compared with those calculated for van der Waals interaction potential.
