Development of photoelectron diffraction of single oriented molecules

本文发展了一种新的基于多重散射X射线光电子衍射（XPD）计算的分子结构测定方法，并应用于几种不同平衡几何构型分子的XPD数据。结果表明，该方法可以确定分子结构参数。我们建立了一个新的实验方案，它由光电子速度图成像谱仪和定向分子样品气组成。分子取向由强激光场控制。

We have developed a new molecular structure determination method, based on multiple-scattering x-ray photoelectron diffraction (XPD) calculations.This method has been applied to our XPD data of several molecules having differentequilibrium geometries. Then, it has been confirmed that by our method the parameters of molecular structure can be determined. We have constructed a new experimental scheme, which consists of a photoelectron velocity map imaging spectrometer and sample gas of oriented molecules. The molecular orientation was controlled by the strong laser field.
