本文综述了铁离子与中性氢、氢和氦的电荷交换过程的实验和理论数据，并对其进行了评价。提供了一个参考书目，列出了现有的数据来源，以及有用的数据汇编和评论文章。适当的标度律，并估计其精度为这些系统。结果表明，对于H和H_2靶，所有Fe ~（q+）离子（q ≥ 5）的总电荷交换截面数据都可用一个简单的解析式表示，其精度为20- 25%。由于没有铁的数据，基于其他离子种类的数据，给出了Feq+ + He电荷交换的估计准确度为50-80%的类似公式。标度公式已被进一步推广，以考虑到对中性目标的电离势的横截面的依赖性。电子捕获到特定的量子态的离子进行了讨论。
The experimental and theoretical data which are available for charge exchange processes involving iron ions and neutral H, H2 and He are reviewed and evaluated. A bibliography is given of available data sources, as well as of useful data compilations and review articles. Appropriate scaling laws are presented, and their accuracy estimated for these systems. It is found that, for H and H2 targets, the total charge exchange cross-section data for all Feq+ ions with q ≥ 5 can be represented by a simple analytical formula with an accuracy of 20–25%. A similar formula with an estimated accuracy of 50–80% is given for Feq+ + He charge exchange, based on data for other ionic species, since no iron data are available. The scaling formulae have been further generalized to take into account the dependence of the cross-section on the ionization potential of the neutral target. Electron capture into specific quantum states of the ion is also discussed.
