本文介绍了一种计算角分辨光电子、俄歇电子和菊池电子衍射花样的全多重散射方法。该方法是特别有用的范围内的电子动能从约50 eV到几千eV。利用有限的实验角分辨率的近似，并且，对于较高的电子动能，占主导地位的电子前向散射，实施，并可用于提高计算效率。计算结果与Cu（001）表面的LVV俄歇衍射实验结果的比较表明，计算结果与实验结果非常吻合
A full multiple-scattering method is described for the calculation of angle-resolved photoelectron, Auger-electron, and Kikuchi-electron diffraction patterns. The method is particularly useful for the range of electron kinetic energies from about 50 eV to a few thousand eV. Approximations that take advantage of the finite experimental angular resolution, and, for the higher electron kinetic energies, the dominant electron forward scattering, are implemented, and may be used to improve computational efficiency. Comparisons of calculations with an experimental LVV Auger diffraction pattern from a Cu(001) surface show excellent agreement
