Electron momentum spectroscopy is a technique that resembles playing pool with electrons. This technique, largely developed in Australia, determines the binding energy and velocity distribution of electrons in matter. This distribution, closely related to the quantum mechanical wave function of the electrons, can be compared directly with calculations of the electronic structure. Such a comparison helps establish which theory approaches nature most closely, and thus improves our understanding of the electronic structure. This understanding helps to predict the properties of materials, and hence this knowledge will facilitate the design of materials with desirable properties.

电子动量谱是一种类似于用电子玩台球的技术。这项技术在很大程度上是在澳大利亚开发的，它决定了电子在物质中的结合能和速度分布。这种分布与电子的量子力学波函数密切相关，可以直接与电子结构的计算进行比较。这样的比较有助于确定哪种理论最接近自然，从而提高了我们对电子结构的理解。这种了解有助于预测材料的性能，因此这种知识将有助于设计具有所需性能的材料。
