Three-body approach to the atomic reactions of electron transfer. Pt. 2

The previous paper proposed an approach to the calculation of electron transfer reactions in ion-atomic collisions based on the Alt-Grassberger-Sandhas three-body equations for the purely Coulomb interaction. In the present paper the equations derived in the previous paper are solved numerically for concrete charge-exchange reactions. The effective potential of the problem is taken in its lowest order approximation which corresponds to the 'pole' electron transfer amplitude. The total and partial cross sections and a few other characteristics of the reactions H+ + H → H + H+, H+ + He(1s2) → H + He+(1s), He2+ + H → He+ + H+ and Li3+ + H → Li2+ + H+ are calculated in a wide range of collision energies from 0.1-100 keV amu-1.
