Electron capture in collisions of He2+ with Li atoms and of Li3+, C6+, and O8+ with He atoms in the high-energy region

Abstract
A method has been developed for the evaluation of the Coulomb integrals containing the product of the Coulomb wave function with Slater-type orbitals which serve as the basis set in constructing the wave function of multielectron atoms within the self-consistent-field approximation, in terms of the Gauss hypergeometric function for an arbitrary nlm state. Analytical expressions are derived for the integrals in closed form irrespective of either the triad nlm or of the quantization axis. This method has been applied in the framework of continuum distorted-wave approximation to obtain the charge-transfer cross section in various collision cases involving heavy stripped ions and multielectron targets. The calculated results are found to be in good agreement with the recent experimental findings and the existing theoretical calculations in the high-energy region.
