Abstract
Determination of the structure of biological particles, randomly oriented in solution, from spatial correlation analysis of fluctuations in x-ray scattering has recently been proposed. The feasibility of scattering fluctuation measurements was evaluated by using an x-ray synchrotron radiation camera to obtain the spatial correlation for a solution of tobacco mosaic virus along a line. The experimental system, analysis of data, and requirements for the determination of structures in solution are discussed using this example.
摘要
最近有人提出，通过对X射线散射波动进行空间相关性分析，来确定溶液中随机取向的生物颗粒的结构。利用X射线同步辐射相机沿着一条线获取烟草花叶病毒溶液的空间相关性，以此评估散射波动测量的可行性。本文以该实例讨论了实验系统、数据分析以及确定溶液中结构的要求。
