Processes involving electrons

Quantitative data on cross sections and rate constants of processes with the participation of electrons are of great importance for kinetic modeling in gas discharge, lighting, gaseous lasers, plasma chemistry, and plasma processing. Model approaches to evaluating the cross sections and rate constants of processes involving electrons are based on qualitative physical ideas about the mechanisms of interaction between the incident electron and the atomic or molecular target. The  elastic scattering, dissociation, and excitation processes are treated within the framework of the Born approximation, corrected by taking into account the set of available experimental data. The processes performed through the formation of a temporary compound are processed within the framework of the Breit–Wigner model using quantum chemical data on the width of the relevant state. Processes involving electrons can be divided into following fields:

    • Differential scattering cross section
    • Total scattering cross section
    • Transport scattering cross section
    • Excitation of an atom into optically allowed state
    • Excitation of an atom into optically forbidden state
    • Rotational excitation of molecules
    • Vibrational excitation of molecules
    • Electronic excitation of molecules
    • Electron impact dissociation of molecules
    • Direct collision ionization
    • Stepwise electron impact ionization
    • Dissociative ionization
    • Penning ionization
    • Ionization involving an excited atom
    • Associative ionization
  • Recombination of charged particles
    • Ion neutralization in pairwise collisions
    • Ion neutralization in three particle collisions
    • Dissociative recombination of an electron and molecular ion
    • Three-particle electrons-ions recombination
  • Attachment and detachment
    • Dissociative attachment of electron and a molecule
    • Attachment of an electron to a complex molecule
    • Attachment of an electron at three particle collisions
    • Detachment in heavy-particle collisions
    • Detachment in collisions with electrons
  • Radiation line broadening in collisions with electrons
