Abstract

The cross section σ_CID for the collision-induced dissociation of a diatomic molecule (or ion) by atomic impact in the post-threshold energy region is found to be of the form σ_CID α(E_tot-E₀)^5/2/E_tr, where E_tr is the initial relative translational energy, E_tot the total (translational + internal) energy, and E₀ the endoergicity (or threshold energy). The power 5/2 is a direct consequence of the 3-body final state of the CID process.
