作为量子力学的基本概念之一，原子和分子中的电子被分配到各自的轨道上。这些轨道的几何分布直接关系到系统的许多化学和物理性质。因此，直接测量电子轨道一直是人们迫切需要的。在这项研究中，我们展示了如何结合光电电子显微镜和同步加速器紫外线光源来记录三维层析成像数据，并提出了一个详细的程序来重建实际空间中正在研究的轨道。
As one of the fundamental concepts of quantum mechanics, electrons in atoms and molecules are assigned to respective orbitals. The geometric distribution of these orbitals is immediately connected to many chemical and physical properties of the system. Consequently, measuring electron orbitals directly has been highly desired. In this study, we demonstrate how a combination of a photoemission electron microscope with a synchrotron UV-light source can be utilised to record a three-dimensional set of tomographic data and present a detailed procedure to reconstruct the orbitals under investigation in real space.
