摘要 利用经典的过势垒电离模型(COBI)方法和轨道计算,模拟了He+离子与正电子碰撞的电离过程。计算的He~+电离截面与其它理论数据一致。此外,我们还发现He的双电离与正电子-He~+碰撞有一定的联系。这一结果可以解释为什么在我们以前的研究中,双电离的He似乎被He+的其余部分正电子散射。COBI模型也被扩展到研究正电子-Ne碰撞引起的双电离。我们的理论结果与实验数据一致。 图形摘要
Abstract The classical over-barrier ionization model (COBI) method and trajectory calculations were utilized to simulate the ionization of He+ impacted by a positron. The calculated ionization cross sections of He+ agree with other theoretical data. Additionally, we found that the double ionization of He has a definite association with the positron-He+ impact. This result can explain why doubly ionized He seemed to be positron-scattered by the rest of the He+ in our previous study. The COBI model was also extended to study the double ionization caused by positron-Ne impacts. Our theoretical results agree with the experimental data. Graphical abstract
