In this section, we shaU outline a many-electron treatment of charge transfer, similar in spirit to that of Tully, which enables different charge-exchange mechanisms to be incorporated in the formalism simultaneously. Although we shall concentrate on the TDAN model of resonant neutralization and negative ionization, we shall indicate how other neutralization processes can be included, and the approach for the reverse process of positive ionization will be fairly apparent. 

The chemisorption process has its maximum cross section at 11 eV in contrast with cross sections for the radiolysis of bulk ice. This difference was understood as being dependent on the selective quenching of dissociative electronic states of water due to the resonant charge exchange between the substrate and adsorbate and the absence of multiple inelastic scattering in the H2O bilayer on Si(lll). 

This formula, obtained by Sena [17], correctly describes the dependence of the resonance charge exchange cross-section on the velocity of the colliding... 

The quantitative theory of resonance charge exchange has been developed by Firsov [18]. The basis for calculations was the fact that, when the energies of the colliding particles relative motion are small, the solution of the time-dependent Schrodinger equation appears to be the wave function ... 

These formulae, obtained by Firsov [18], are widely used to calculate the resonance charge exchange cross-sections [19]. A typical example, demon-...

The second step in this reaction chain is resonant (comparable to resonant charge exchange between H-atoms and protons), if the molecules are vibrationally excited in the v = 4 level. 

The process of charge exchange occurs by capture of a bound electron from neutral hydrogen by H-like ions followed by radiative decay. As in the case of radiative recombination or cascades in He-like ions, the contribution of charge transfer is stronger to the triplet lines than to the resonance line w. The emission via charge-transfer is determined by ...
