Qualitative differences have been observed between two types of "quasi-one-electron" collision systems. We have studied valence-electron excitation at "high" energy (relative collision velocities up to 0.5 a.u.) in the Mg + +He and Na + +H collision systems, and find that while Mg + +He collisions are dominated by "direct" excitation, the Na + +H collisions exhibit significant "molecular" excitation, even at the highest velocities. This behavior can be understood in terms of the moleculardoi:10.1103/physreva.36.3475 pmid:9899275 fatcat:42voom3utbdtbiyp7eiw2ipzs4
