本论文介绍了一种新的实验装置，结合了传统的流动余辉系统的化学多功能性与漂移管的能量可变性的建设和操作。这允许测量先前未测量的正离子和负离子迁移率。离子迁移率测量对离子中性分子间势提供了重要的约束，因此在测试经验或量子力学理论中具有价值。本文给出了He ~+、He ~（2+）、H ~+、D ~+、O ~+、N ~+、Ar ~+、H ~（2+）、H ~（3+）、H ~（2+）、H ~-、O ~-、OH ~-在He中的迁移率和H ~（3+）在H_2中的迁移率。以下论文描述了在同一设备中测量正离子-中性和负离子-中性反应速率常数。
The present paper describes the construction and operation of a new experimental device that combines the chemical versatility of a conventional flowing afterglow system with the energy variability of a drift tube. This allows the measurement of both positive and negative ion mobilities not previously measured. Ion mobility measurements offer a significant constraint upon the ion‐neutral intermolecular potential and are therefore of value in testing either empirical or quantum mechanical theory. The mobilities of He+, He2+, H+, D+, O+, N+, Ar+, H2+, H3+, H2+, H−, O−, and OH− in helium and H3+ in H2 are presented in the present paper. The following papers describe positive ion‐neutral and negative ion‐neutral reaction rate constant measurements in the same device.
