用双中心原子轨道紧耦合方法计算了C⁴⁺-He以及O⁶⁺-He碰撞的单俘获总截面，入射离子的能量范围为10～100keV／amu，所得计算结果在实验误差范围内与实验值很好符合。对满壳层入射离子，研究了单俘获截面随入射离子电荷态的变化，并讨论了原子轨道展开波函数数目对计算结果的影响。

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.
