Inelastic Electron Scattering and Soft X-Ray Emission Spectroscopy of Solids

实验旨在利用非弹性电子散射（IES）和软x射线发射（SXE）光谱学来理解固体电子结构的各个方面。测量了宽能量范围内的电子激发，从而可以对数据进行Kramers-Kronig分析。通过研究谱特征的动量传递依赖性，可以得到动力学效应。所使用的系统有几个独特的功能，包括低温样品夹，原位离子清洗和俄歇分析，以及不干扰特高压环境的样品转换器。乐器开发是该计划的一个补充方面。此外，在NIST和NSLS使用同步加速器源进行了研究。

Experiments are directed towards understanding various aspects of the electronic structure of solids using Inelastic Electron Scattering (IES) AND Soft X-ray Emission (SXE) Spectroscopy. The electronic excitations over a wide energy range are measured which allows Kramers-Kronig analyses of the data to be carried out. Dynamical effects may be obtained by studying the momentum-transfer dependence of the Spectral features. The systems utilized have several unique features, which include low temperature sample holders, in situ ion cleaning and Auger analysis, and sample changers which do not disturb the UHV environment. Instrumental development is a complementary aspect of the program. In addition, studies are made using synchrotron sources at NIST and NSLS.
