Mutual neutralization in rare gas halides

The cross sections for mutual neutralization in Ne++F−, Ar++F−, and K++Cl are obtained from two-state close coupling calculations. The Landau–Zener approximation gives adequate results in each case. The rate of neutralization is studied as a function of ambient gas density. Near atmospheric pressure, mutual neutralization is more likely than excimer formation of Ne++F− collisions, but less likely in Ar++F− collisions.
