We discuss in detail the Bloch waves method for the calculation of energy and orientation dependent scattering cross-section for inelastic scattering of electrons on crystals. Convergence properties are investigated and a new algorithm with superior timing and accuracy is described. The new method is applied to calculations of intensity of weakly excited spots, maps of magnetic signal, and tilt series from zone axis orientation towards three-beam orientation.
我们详细讨论了 Bloch 波方法，用于计算电子在晶体上非弹性散射的能量和方向相关散射截面。研究了收敛特性，并描述了一种具有优越的定时和精度的新算法。新方法应用于弱激发斑点强度、磁场信号图以及从晶带轴取向到三轴取向的倾斜系列的计算。
