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.

电子动量光谱法是一种类似于电子泳池的技术。 该技术在澳大利亚大部分开发，决定了物质中电子的结合能和速度分布。与电子结构的计算直接比较了与电子的量子机械波函数密切相关的这种分布。这样的比较有助于确定哪种理论方法最紧密，从而提高了我们对电子结构的理解。这种理解有助于预测材料的特性，因此，这些知识将促进具有理想特性的材料的设计。
