Attachment energy, description

The fluid model is a description of the RF discharge in terms of averaged quantities [268, 269]. Balance equations for particle, momentum, and/or energy density are solved consistently with the Poisson equation for the electric field. Fluxes described by drift and diffusion terms may replace the momentum balance. In most cases, for the electrons both the particle density and the energy are incorporated, whereas for the ions only the densities are calculated. If the balance equation for the averaged electron energy is incorporated, the electron transport coefficients and the ionization, attachment, and excitation rates can be handled as functions of the electron temperature instead of the local electric field. 

Approximate propagators may be designed to provide perturbative corrections to Koopmans results or may have the flexibility to account for correlation states where Ih or Ip descriptions of final states are qualitatively invalid. For the first case, in which the one-electron picture of electron detachment or attachment is adequate, quasiparticle self-energy approximations are suitable. In other cases, nondiagonal self-energy approximations are necessary. 

With the exception of carbohydrate-binding modules attached to glycosi-dases, the book does not cover those interactions of carbohydrates with proteins that do not lead to covalency changes. The thinking behind the omission is that the interactions are weak and often polyvalent, and that the free energy changes involved are below the resolution of physical organic chemistry, even if detailed qualitative descriptions of some interactions are...
