The classical trajectory Monte Carlo (CTMC) simulation method has been employed to study the sub-shell distributions of total charge transfer cross sections and total ionization cross sections in collisions of partially stripped ions of carbon, nitrogen and oxygen in different charge states (q ⩽ 5) with ground state atomic hydrogen in the energy range 10-200 keV amu-1. The total cross section for charge transfer and ionization has been found to be in good agreement with the experimental observations as well as with other theoretical findings. Due to the non-availability of any other experimental results for sub-shell distributions of charge transfer cross sections, comparisons have been made with other existing theoretical results. The observations have been found to be satisfactory. However, an oscillatory structure of the charge-state dependence of the total cross sections has not been found in our calculation.

We have calculated the electron excitation cross sections of hydrogen atom by the impact of protons, alpha particles and He + ions using the boundary corrected continuum intermediate state approximation in the intermediate and high energies. The calculated results are compared with other theoretical and experimental results. The angular influence of excitation to the H atom at the intermediate energy is also discussed. The distortion effects due to the projectile charges in reactions of electron excitation to bound states of the target H atom are shown in the intermediate and high collision energy.
