中文摘要：
在准相对论理论框架下计算了Cu^18＋离子的双电子复合截面，分析了组态相互作用对截面的影响．基于这些数据，在冲量近似下，通过对靶原子中电子动量分布的卷积，进一步得到了Cu^18＋与H2碰撞过程中的共振转移激发截面，并与已有的实验结果作了比较，符合得很好．
英文摘要：
The dielectmnic recombination cross sections of Cu^18＋ ions are calculated using a quasi-relativistic theory. The effects of configuration interaction to the cross sections are analysed. Base on the calculated data, the resonant transfer excitation cross sections of Cu^18＋ with H2 targets are estimated by using the convolution of Compton profile of the target electron in the impulse approximation. Good agreement of the present calculation with new experimental observation is achieved.
