Collision-time asymmetry and speed-dependent effects on the Cd-114 326.1 nm line penturbed by Kr

Using a laser-induced fluorescence method, detailed analysis of profiles of the Cd-114 326.1 nm line perturbed by krypton was performed which revealed departures from the ordinary Voigt profile. These departures are shown to be consistent with fits of experimental profiles to a speed-dependent asymm etric Voigt profile. Coefficients of the pressure broadening, shift, and co llision-time asymmetry are determined and compared with those calculated in the adiabatic approximation for the van der Waals, Czuchaj-Stoll, and Mors e potentials.
