A classical approach to dissociative electron attachment DA: application to temperature effects in the DA cross section of CF3Cl

A classical theory of dissociative attachment (DA) is developed. The DA cross section σ_{ν → DA} of a molecule in the initial vibrational state ν is calculated. The model is applied to the negative ion formation in low energy electron scattering from CF₃Cl molecules. Temperature effects of the DA cross section of CF₃Cl can be explained within our classical model.
