Three-body approach to the atomic reactions of electron transfer. II. Calculation of total cross sections

For pt.I see ibid., vol.23, p.2309 (1990). 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 I 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 to H+H + , H + +He(1s 2 ) to H+He + (1s), He 2+ +H to He + +H + and Li 3+ +H to Li 2+ +H + are calculated in a wide range of collision energies from 0.1-100 keV amu -1 .
