Abstract
We have determined reduced absorption coefficients on far wings of the Ba 6s2 1S0-5d6p 1P1 line broadened by He, Ne, Ar, Kr, and Xe. Using the unified Franck-Condon theory, we analyzed the blue satellite band observed for each of the He, Ne, and Ar perturbers and obtained the position and the height of the extremum of the difference potential-energy curve to be 6.5 ± 1.5 A and 251 ± 4 cm-1 for He, 7.6 ± 2 A and 114 ± 2 cm-1 for Ne, and 7.4 ± 2 A and 70 ± 2 cm-1 for Ar. We have also observed the collision-induced-dipole absorption bands associated with the Ba 6s2 1S0-6s7s 1S0 forbidden transition for all rare-gas perturbers.
