Superelastic Collisions and Electron Energy Distribution Function

  • Chapter
Fundamental Aspects of Plasma Chemical Physics

Part of the book series: Springer Series on Atomic, Optical, and Plasma Physics ((SSAOPP,volume 85))

  • 1937 Accesses

Abstract

The Chapter focuses on the role of inelastic and second-kind (superelastic) collisions in shaping the electron energy distribution function (eedf). Particularly important are the second-kind collisions, which create structures on the eedf, such as peaks and plateaux, also experimentally observed. This non-equilibrium behavior is reflected on the rate coefficients of electron induced processes, in particular dissociation and ionization.

Notes

  1. 1.

    This principle assure the existence of the equilibrium distribution.

  2. 2.

    We should note that \( S_{sup}^{2}(\varepsilon ) = -S_{sup}^{1}(\varepsilon -\varepsilon ^{\star }) \) and \( S_{in}^{2}(\varepsilon ) = -S_{in}^{1}(\varepsilon +\varepsilon ^{\star }) \).
