In recent years, highly accurate measurements of photoelectron holograms have become possible through the development of electron energy analyzers with an energy range of 300–1000 eV. Effects of the inelastic mean free path (IMFP) and thermal vibration became apparent in the hologram pattern. For example, the quasi‐Kikuchi band is clearly observed, which cannot be explained by conventional multiple scattering theories. Herein, the theory of photoelectron holograms is summarized, considering the inelastic scattering (IES) and thermal vibration effects. Furthermore, the simulated hologram is compared with a diamond hologram measured at a kinetic energy of 563.4 eV. It is also shown that the formation mechanism of the quasi‐Kikuchi band differs from that of the normal Kikuchi band.

考虑非弹性平均自由程和拟菊池能带形成机理的高角度分辨光电子全息理论

近年来，通过开发能量范围为300–1000 eV的电子能量分析仪，可以对光电子全息图进行高精度测量。在全息图模式中，非弹性平均自由程（IMFP）和热振动的影响变得明显。例如，可以清晰地观察到准菊池带，而传统的多重散射理论无法解释。在这里，总结了光电子全息图的理论，其中考虑了非弹性散射（IES）和热振动效应。此外，将模拟全息图与在563.4 eV动能下测得的钻石全息图进行比较。还表明准菊池带的形成机制与正常菊池带的形成机制不同。
