N2 - Landau-Zener-Stueckelberg (LZS) and two-state JWKB calculations have been made using Rittner model potentials simulating (Na, Li) + 1 → (Na+, Li+) + 1- chemiionization at post-threshold energies. Comparison shows deviations between LZS and JWKB calculations. The S·matrix obtained in the JWKB computation is accurate to at least two significant figures when compared to a fully quantal computation.
