采用细网格二维测量方法对CaF2（111）表面的Ca2p和F1s的X射线光电子衍射（XPED）谱进行了高角分辨率的测量。这些测量揭示了大量的精细结构，包括许多菊池样带和圆形图案。在比较Ca2p和F1s的XPED图案，菊池样带和圆形图案的能量依赖性进行了观察。此外，与（111）平面相关的菊池样带在Ca2p和F1s XPED图案之间存在显著差异。这是第一次报道的地点特异性的菊池样带的XPED。
Fine-mesh two-dimensional measurements of Ca2p and F1s X-ray photoelectron diffraction (XPED) patterns from a CaF2(111) surface were performed with high angular resolution. These measurements revealed a great deal of fine structure including many Kikuchi-like bands and circular patterns. On comparing the Ca2p and F1s XPED patterns, an energy dependence of the Kikuchi-like bands and circular patterns was observed. Furthermore, the Kikuchi-like bands associated with the (111) plane differed substantially between the Ca2p and F1s XPED patterns. This is the first report of the site-specific characteristic of the Kikuchi-like bands in XPED.
