Role of impact parameter in branching reactions: Chemical accelerator studies of the reaction Xe+ + CH4->XeCH3+ + H

Article abstract of DOI:10.1063/1.441716

Integral reaction cross sections and product velocity distributions have been measured for the ion-molecule reaction Xe⁺(CH4,H)XeCH3⁺ over the relative reactant translational energy range of 0.7-5.5 eV by chemical accelerator techniques.The kinematic results indicate that reaction proceeds in a direct manner by a rebound mechanism over the energy range studied, suggesting that this substitution reaction occurs predominantly in small impact parameter collisions.This finding contrasts with the results obtained for the competing reaction, Xe⁺(CH4,CH3)XeH⁺, where the strong forward scattering of the XeH⁺ product indicates that H-atom abstraction occurs primarily in large impact parameter collisions.
