软 X射线共振非弹性光散射及其应用

软 X射线共振非弹性光散射是近年来随着高亮度第三代同步辐射出现而发展起来的光散射光谱技术 ,可以用于对多原子构成的分子、凝聚态物质进行位置选择的价电子态结构的研究。与 X射线光电子能谱 ( XPS)或紫外光电子能谱 ( UPS)相比 ,这一光谱方法由于测量样品激发后产生的散射 X射线 ,因而不仅可以获得表面的原子分子信息 ,而且可以用于研究样品体内或掩埋薄层的原子分子。同时这一方法的共振特性使得其可以进行灵敏的元素选择测量。本文将介绍这一光散射光谱技术及其在原子分子物理、表面物理及凝聚态物理中的应用

Soft X-Ray Resonant Inelastic Scattering and Its Applications

Soft X Ray Resonant Inelastic Scattering, as a new spectroscopic technique developed with the third generation synchrotron radiation, has many advantages in studying valence states in molecules and condensed materials with a position selectivity. Comparing with XPS or UPS, this technique can obtain the information of the atoms and molecules from surfaces, buried layers, as well as bulk materials because of measuring the X ray scattered. Resonant features of specific atoms in X ray scattering also makes this techniques very sensitive in element selectivity. We introduce this technique and discuss its applications in this paper.
