Abstract

A collinear reactive study of the ion-molecule system (Ar +

H_{2}^{+}

{Ar}^{+}

H_{2}

, Ar

H^{+}

+ H) is presented. The main emphasis was directed towards the two reactions

{Ar}^{+} + H_{2} (ν = 0) \to Ar H^{+} + H

and

Ar + {H_{2}}^{+} (ν^{'} = 2) \to Ar H^{+} + H

, which exhibit avoided-crossing features. It is shown that reactive transition probabilities obtained from an exact collinear treatment which incorporated a large number of vibrational states to ensure convergence are reproduced by simple reactive curve-crossing models.
