对辐照气体的电导率的早期测量表明了电荷优先重组的重要性，即在正电荷和负电荷逃离相互场之前进行重组。优先复合的一个重要部分是电子的母离子重获。似乎没有对这一过程进行理论处理。本文详细地讨论了气体中电子的母离子重获的机理。使用两种型号：一种适用于低压和中压，另一种适用于高压。从这项研究看来，基本上所有的优先复合都可以用电子的母离子重获来令人满意地解释。对固体也作了简要的考虑，结果表明，在载流子迁移率小的辐照半导体中，母离子会被捕获。
Very early measurements of conductivity in irradiated gases demonstrated the importance of preferential recombination of charges, i.e., recombination of positive and negative charges before they escape their mutual field. An important part of preferential recombination is the parent‐ion recapture of electrons. No theoretical treatment of this process appears to have been given.In this paper the mechanism of parent‐ion recapture of electrons in gases is considered in some detail. Two models are used: one applicable at low and intermediate pressures and the other applicable at high pressures. It appears from this study that essentially all preferential recombination can be explained satisfactorily in terms of parent‐ion recapture of electrons. A brief consideration of solids is also given and it is shown that parent‐ion recapture is to be expected in irradiated semi‐conductors which have small mobility of charge carriers.
