中文摘要：
应用双中心原子轨道强耦合方法研究了H＋与里德伯态原子Li（5d）碰撞的电荷转移过程,计算了电子转移到氢原子各个n,l壳层（这里n为主量子数,l为角量子数）的态选择截面.结果发现,电荷转移的末态主要分布在与初态电子能量5d接近的n=4—7能级,该分布随碰撞能量的变化不大;但俘获末态的l分布对入射离子能量很敏感：在1keV左右的低能时主要分布在高l的末态,随着碰撞能量增加峰值逐渐向低l方向移动,并在l=1左右达到峰值.
英文摘要：
The charge exchange process in collisions of H^＋ with Li （Sd） is investigated using the two-center atomic-orbital closecoupling method. The state-selective cross-sections are obtained in the energy range of 0.5-10 keV. It is found that the processes for capture to n = 4-7 are the dominant reactions, and the n-distribution of state-selective cross-sections is weakly dependent on the collision energy. But the l-distribution of state-selective cross-sections strongly depends on the collision energy. For the lower collision energy around 1 keV, the l-distribution increases with increasing l. However, the l-distribution moves to the lower quantum number as the collision energy increases, and the maximum value appears around l = 1.
