dc.description.abstract A comparison between ab initio Hartree-Fock and pseudopotential results for interaction potentials between Li and Na and the rare gases He through Ar is made based upon semiclassical analysis of spectral data from the wings of the pressure-broadened resonance lines. The most accurate information is obtained for the difference potentials between the interaction potentials for the excited states and that for the ground state. The line wing intensity is sensitive to the difference potential, but only weakly dependent upon the initial state interaction potential itself. The Hartree-Fock difference potentials are expected to be accurate because the correlation energies in the ground and excited states should be nearly equal. This expectation is supported by our analysis. Comparisons are made to the detailed shape of the red wing of the Li resonance line perturbed by he and to the satellite band positions observed for most of the other Li and Na rare gas combinations. Potentials are taken from the work of Wahl and coworkers, Pascale and Van de Planque, and Bottcher, Cravens, and Dalgarno. Line wing data are taken from the work of Gallagher and coworkers, Lalos and Hammond, Ch’en and Wilson, and Granier and Granier. en_US
