Chemical Binding and Electron Correlation Effect Studied by Inelastic X-Ray and High Energy Electron Spectroscopy
The recent technical advances in high energy electron and the X-ray scattering have made it possible to measure intensities with high accuracy. In particular, the prospect of obtaining a very reliable separate measurement of inelastic X-ray scattering intensities using the recent developments of synchrotron radiation sources, is very exciting. Here we present an overview of the theoretical developments of electron correlation effect on scattering intensities. Examples of experimental and theoretical intensity for a few molecular systems are given and compared. Based on these intensities, electron pair distribution, the exchange and correlation holes are briefly discussed.
