摘要

我们介绍了质子与中性惰性气体原子(即 Ne、Ar、Kr 和 Xe)相互作用中电离和电子捕获过程的经典处理方法。我们使用三体经典轨迹蒙特卡洛(CTMC)方法计算了单电子过程的总截面(TCS)和微分截面(DCS)。CTMC 模型采用了加维型模型势来描述射弹与目标之间的碰撞,并考虑了非活动电子的屏蔽效应。在 0.2 keV 至 50 MeV 的能量范围内,对目标的一些子壳的碰撞能量进行了 TCS 评估。电离 DCS 在 35 keV 的撞击能量下进行了评估,重点只放在外层子壳上。我们发现,对于所有目标,我们的电离和电子捕获 TCS 与之前的理论和实验数据非常吻合。此外,我们还给出了所有碰撞系统中电离电子的单(SDCS)差分截面和双(DDCS)差分截面与能量和抛射角的函数关系。

Interaction of Protons with Noble-Gas Atoms: Total and Differential Cross Sections
We present a classical treatment of the ionization and electron-capture processes in the interaction of protons with neutral noble-gas atoms, namely, Ne, Ar, Kr, and Xe. We used a three-body classical-trajectory Monte Carlo (CTMC) method to calculate the total (TCS) and differential (DCS) cross sections of single-electron processes. The Garvey-type model potential was employed in the CTMC model to describe the collision between the projectile and the target, accounting for the screening effect of the inactive electrons. The TCSs are evaluated for impact energies in the energy range between 0.2 keV and 50 MeV for a number of sub-shells of the targets. The ionization DCS are evaluated for an impact energy of 35 keV, focusing on the outer sub-shells only. We found that our ionization and electron-capture TCSs are in very good agreement with the previous theoretical and experimental data for all targets. Moreover, we presented single (SDCS)- and double (DDCS)-differential cross sections as a function of the energy and ejection angle of the ionized electron for all collision systems.
