Abstract
Calculations are reported of matrix elements of the Baylis-Gombas model potential for Li-He and Li-Ne interactions. Included are comparisons of two computational approaches, one based upon a numerical double-integration procedure, the other an analytical, approximative method. The special emphasis of the calculation is the sensitivity of matrix elements that are important for collision-induced electronic transitions to the precise choice of the Baylis model parameter r0. Also reported and compared to the Baylis results are calculations of Li-He/Ne matrix elements for a Hartree-Fock frozen-core model potential and for two Bottcher-type model potentials.
