Analysis of crystal potential of a single small particle using multiwave-refraction effects of high energy electron

从实验和理论两方面研究了电子多波折射效应在小粒子结构分析中的适用性。以被{211}平面对称包围的a15型Cr小颗粒为例。(1)气体蒸发装置的搭建；(2)电子衍射的多波折射图实验；(3)棱镜晶体电子衍射的多波动力学理论的建立；(4)多折射效应模拟程序的编制；(5)实验与模拟结果的比较。

Applicability of multiwave-refraction effects of electrons to structure analysis of a small particle was studied from experimental and theoretical view points. A15-type Cr small particles symmetrically surrounded by{ 211} planes were treated as an example.(1) construction of gas-evaporation apparatus,(2) experiment of multiwave-refraction pattern using electron diffraction,(3) formulation of multiwave dynamical theory of electron diffraction for a prism-shaped crystallite,(4) programming of multi-refraction effect simulation, and(5) comparison between the experiment and the simulation were carried out.
