Abstract
Abstract The absorption profile and the temperature dependence of the Cd line at 326.1 nm perturbed by Xe at a density of about 1 × 1019 atoms cm−3 have been carefully studied over a spectral range extending from 750 cm−1 in the blue wing to 1400 cm−1 in the red wing using a high resolution double beam spectrometer. Interatomic potentials for CdXe in the ground electronic state 1O+ as well as the exited (3O+ and 31) states have been deduced from the spectrum. The van der Waals coefficient differences ΔC06 and ΔC16 are also obtained. The well depths for the ground 1O+ and the exited (3O+ and 31) states are found to be 192±18, 988±41 and 152±15 cm−1 respectively. The position of the ground state potential well minimum is deduced using the combination rule of Kong and Chakrabarty. The obtained well depth with their allowable errors are in good agreement with the values obtained before for the CdXe system from other experimental methods.
