Atom Location by Channelling Enhanced Microanalysis using Inner-shell Electron Energy Loss Spectroscopy. The technique of Atom Location by Channelling Enhanced Microanalysis (ALCHEMI) has been explored extensively using Electron Energy Dispersive X-ray (EDX) measurements by many authors. The extension of this method to Electron Energy Loss Spectroscopy (EELS) is difficult due to the more complicated formulation of inner-shell ionization required under such experimental conditions. Issues such as the "delocalization" of the ionization interaction and the significance of channelling of the scattered electron need to be addressed so that this method may be generally applicable. It is the aim of this project to extend this commonly used method to the topical field of EELS.

利用内壳电子能量损失谱的通道增强微分析的原子定位。许多作者利用电子能量色散x射线（EDX）测量对通道增强微分析（ALCHEMI）原子定位技术进行了广泛的探索。将该方法推广到电子能量损失谱（EELS）是困难的，因为在这种实验条件下需要更复杂的内壳电离公式。需要解决诸如电离相互作用的“离域”和散射电子通道的重要性等问题，以便该方法可能普遍适用。这个项目的目的是将这种常用的方法扩展到EELS的主题领域。
