Maximum in the translational energy dependence of the cross section for the Na+CH3I→NaI+CH3 reaction

Abstract
Relative values of the total reaction cross section for the crossed molecular beam reaction Na+CH3I→NaI+CH3 have been measured over the collision energy ET range of 0.11–0.40 eV. The measured excitation function is of a mechanistically bimodal type showing a maximum at ET ∼0.14 eV. This functionality is compared to those of closely related reactions and is discussed in the light of different dynamical models.
