| Abstract: | The single electron capture cross sections for the collisions of the multiply charged C4 and O6 ions with helium in the impact energy range of 10 - 100 keV/amu are calculated using the two-centre atomic orbital close-coupling method. The calculated results are compared with the experimental data and other calculations. The present calculations are in good agreement with experimental data. The influence of the number of the basis function to the calculation is discussed. It is found that the calculation should only include the main states, and the increase of the number of the basis function cannot improve the accuracy of the calculation remarkably. |
