摘要
利用近代物理研究所新建的原子物理实验平台,采用位置灵敏探测和散射离子 反冲离子飞行时间符合技术,研究了180keV的Ar9+离子与Na原子碰撞中的多电子转移过程,对实验结果做了分析和简单的讨论,并同修正后的分子库仑过垒模型结果进行了比较。
Using the new built research facility for atomic physics in Institute of Modern Physics, multiple electron transfer processes were studied in the collisions of Ar^(9+) ions with Na atoms at 180 keV. A combination of position sensitive and time-of-flight techniques was used. 8 reaction channels are identified from the experimental data and the results were compared with the predictions of the molecular Coulombic overbarrier model by considering the autoionization decay and electron evaporation of multiply excited states in projectiles and recoil ions respectively.
