Correlation spectroscopy with coherent X-rays

X-ray photon correlation spectroscopy (XPCS) is a novel technique for the study of slow dynamics in disordered materials. It overcomes limitations of visible light scattering techniques such as multiple scattering or limitations in Q-range by using coherent X-rays from third generation synchrotron radiation sources. Applications to the static and dynamic behavior of complex fluids and to slow dynamics in hard condensed matter systems are reviewed. (C) 2003 Elsevier B.V. All rights reserved.
