Abstract

Three-Coulomb wave model (3C) is used to investigate the angular distributions of electron ejected from ground state atomic hydrogen by the impact of 1 MeV/amu and 2.5 MeV/amu C6+ions and 95 keV H+ ions. The final state wavefunction incorporates distortion due to three-body mutual Coulombic interaction. The forward-backward angular asymmetry in the low energy electron emission has been studied. The present computed results have been compared with the available experimental results and with the theoretical calculations using alternative methods. We found that our computed results are in good agreement with the experimental observations compared to other theoretical findings. DDCS peak is reproduced by the present calculation and is verified by CDW-EIS theory for C6++ H collision. In addition, DDCS results for ionization are given in tabular form.
