高电荷态Arq+与Ne碰撞中入射离子电荷交换截面的研究
Projectile charge exchange cross sections measured in low energy Arq+-Ne collisions
摘要
报道Arq++Ne(q=8, 9, 11, 12)碰撞体系中多电子转移过程,得到了多组实验测量电荷交换截面数据,讨论入射离子电荷交换截面、反冲离子产生截面与入射离子电荷态、能量以及散射离子电荷态的关系,并且将实验结果与Arq++Ar碰撞体系进行对比研究.在修正分子库仑过垒模型的基础上,对实验现象做了合理的解释.
Abstract
The projectile charge exchange cross sections, recoil ion production cross sections, and the total charge exchange cross sections are measured by using coincidence techniques. The dependences of the cross sections on the impact energies, the projectile charge states, the recoil ion charges states, and the number of transferred electrons are discussed, respectively. Based on the modified MCBM model, the experimental results are understood reasonably.
