Reactions of He2+, Ne2+, Ar2+, and Rare-Gas Hydride Ions with Hydrogen at 200°K

The flowing afterglow technique has been used to measure rate coefficients for the reactions of the rare-gas molecular ions X2+, XH+, XH2+, and X2H+ (where X = He, Ne, and Ar) with hydrogen at 200°K. An attempt was made to establish the product channels for these processes.
