Abstract

The orientation dependence of the barrier to reaction is incorporated into the classical line-of-centers model to obtain the dependence of the "cone of acceptance" upon impact parameter and collision energy. Simple expressions for the orientation-averaged opacity function, the reaction cross section and the steric factor are derived. Comparison is made with recent classical trajectory calculations by Blais and Truhlar for the H + D₂ reaction.
