Charge transfer in collisions of atomic hydrogen with N^{7+} ions in the highenergy region
Abstract
A method to calculate electroncapture cross sections for collisions between an arbitrary n_{i}l_{i}m_{i} shell of a hydrogenic target and an arbitrary n_{f}l_{f}m_{f} shell of a fast bare projectile has been developed in the framework of the continuum distortedwave 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 N^{7+}+H(1s) collisions are calculated in the energy range between 10 and 40 MeV and compared with existing theoretical calculations. The total chargetransfer cross sections have been evaluated by applying an n^{3} law for n>=7 levels.
