Radiative collisional processes for atoms and ions

We describe theoretical studies of radiative collisional processes between atoms and ions. The cross sections and rate coefficients for the radiative charge transfer process between a carbon atom and a helium ion (C-He${}^+$) [1] and between other atom-ion pairs are calculated. The radiative association process is investigated for a carbon atom and a proton (C-H${}^+$) and for other atom-ion systems. Applications of the results are discussed. [1] J.F. Babb and B. M.
