我们研究了发射波的角动量特性对俄歇电子衍射图的影响，以及对发射体附近散射原子全息再现像形成的影响。我们发现，这对重建图像的性质的影响与原子散射因子的各向异性一样大。在散射因子的情况下，参考波的各向同性是良好图像重建的最佳形式
We investigate the effect of the angular-momentum character of the emitted wave on Auger electron diffraction patterns, and on the form of holographically reconstructed images of scattering atoms in the vicinity of the emitter. We find that this can have as much effect on the nature of the reconstructed image as the anisotropy of the atomic scattering factors. As in the case of the scattering factors, isotropy of the reference wave is the optimum form for good image reconstruction
