The Raman Emission by X-rays (REX-I) Workshop focused on Raman Scattering of x-rays mostly from Synchrotron Radiation Sources. The advent of new high brightness sources of x-ray radiation has given new impetus to this tantalizing technique that has offered ways of obtaining new insights into the atomic and electronic structure of solids and gases, but which has been limited by weak sources of excitation. In the last five years, Raman scattering by x-rays has been observed an ubiquitous phenomena. It has been applied to yield new information about the band structure of solids and about the...
