液氦中的正常负离子由一个电子组成,该电子被限制在半径约为19?的气泡中。这些气泡已经在许多实验中进行了研究。飞行时间迁移率测量显示,还有其他类型的负离子具有更高的迁移率和未知的结构。在这本笔记中,我们报告了对其中最快的一种情况的研究,并讨论了在什么条件下可以观察到它。
The normal negative ion in liquid helium consists of an electron confined in a bubble of radius approximately 19 Å. These bubbles have been studied in many experiments. Time-of-flight mobility measurements have revealed that there are other types of negative ion of higher mobility and unknown structure. In this note we report on a study of the fastest of these and discuss the conditions under which it can be observed.
