Reevaluation of electron-capture cross sections in C4++H collisions

We calculated the total electron-capture cross section for collisions of C4+ ions With atomic hydrogen in the energy range of 10-2000 eV/nucleon using the close-coupling two-center atomic orbital expansion method. Various basis sets have been used to check the convergence of the calculation and the results are shown to be in general agreement with existing experimental data. However, we found no evidence of a dip in the total electron-capture cross sections near 500 eV/nucleon as reported by Bliek ct al.
