Inelastic X-Ray Scattering in Condensed Matter Systems

Abstract
Scattering experiments have given us much of what we know about the microscopic behavior of an enormous variety of condensed matter systems. Simple but fascinating materials such as solid and liquid helium,transition metals such as iron and nickel,semiconductors such as silicon and gallium arsenide, complex oxides such as V 2 O 3 and high‐temperature superconductors, and even more complex solids such as protein crystals have all been investigated by a variety of scattering probes. Advances in synchrotron sources of hard x rays promise to open a new frontier in the use of inelastic scattering to probe eV and sub‐eV electronic excitations in simple and complex solids and liquids.
