摘要：

At relatively high electron energies, the patterns observed in X-ray photoelectron diffraction (XPED) for light solids are dominated by "bands" corresponding to the main crystallographic planes in the crystal. These bands can be termed "Kikuchi-like" and occur for the same reasons that give rise to the well-known Kikuchi bands in electron diffraction. In the present work we examine in detail the fine mesh XPED pattern from the CaF2(111) surface by using the single scattering cluster-spherical wave theory (SSC-SW). We find that the theory reproduces well the main Kikuchi-like characteristics of the observed pattern and is sensitive to the size of the diffracting domains. (C) 1997 Elsevier Science B.V.
