§16§This book deals with the application of grazing angle x-ray§and neutron scattering to the study of surface-induced§critical phenomena. With the advent of even more advanced§synchrotron radiation sources and new sophisticated§instrumentation this novel technique is expected to§experience a boom.§The comprehensive and detailed presentation of theoretical§and experimental aspects of the scattering of evanascent§x-ray and neutron waves inside a solid makes this book§particularly useful for tutorial courses.§Particular emphasis is put on the use of this technique to§extract microscopic information (correlation functions) fromthe real structure of a surface, from buried and magnetic§interfaces and from surface roughness. §04§Evanescent X-ray scattering.- Evanescent neutron scattering.- Semi-infinite critical systems.- Surface effects at first order phase transitions.
