Charge transfer in collisions of atomic hydrogen with N7+ ions in the high-energy region
Abstract
A method to calculate electron-capture cross sections for collisions between an arbitrary nilimi shell of a hydrogenic target and an arbitrary nflfmf shell of a fast bare projectile has been developed in the framework of the continuum distorted-wave approximation. Analytical expressions are derived for the Coulomb integrals in closed form in terms of Gauss hypergeometric functions in a terminating series. As an application, the cross sections in N7++H(1s) collisions are calculated in the energy range between 10 and 40 MeV and compared with existing theoretical calculations. The total charge-transfer cross sections have been evaluated by applying an n-3 law for n>=7 levels.
