X-ray Anomalous Scattering

Overview

This document is intended to serve both as an introductory tutorial to anomalous scattering and as a general tool for designing experiments based on anomalous scattering. While primarily intended for crystallographers considering MAD data collection, it may also be of some help in planning experiments using spectroscopy (XAFS, DAFS) or small-angle scattering.
