摘　　要：使用位置灵敏技术和飞行时间方法研究了低能高电荷态氩离子与氩原子的碰撞反应,给出了实验测量得到的入射离子电荷交换截面和转移电荷截面,研究了反应截面与不同电荷态参教的关系,并与修正后的分子过垒模型计算结果进行了比较。The reactions of collision between highly charged Argon ions and Argon atoms at low energy have been studied by using position-sensitive and time-of-flight technology. The cross sections of projectile charge exchange and charge transfer were obtained. The relations between reaction cross sections and projectile charge states were studied and compared with the theoretical results of revised Molecular Over Barrier model.
