## Neutrons, X-rays and Light: Scattering Methods Applied to Soft Condensed MatterScattering experiments, using X-ray, light and neutron sources (in historical order) are key techniques for studying structure and dynamics in systems containing colliods, polymers, surfactants and biological macromolecules, summarized here as soft condensed matter. The education in this field in Europe is very heterogeneous and frequently inadequate, which severely limits an efficient use of these methods, especially at large-scale facilities. The series of "Bombannes" schools and the completely revised and updated second edition of the lecture notes are devoted to a practical approach to current methodology of static and dynamic techiques. Basic information on data interpretation, on the complementarity of the different types of radiation, as well as information on recent applications and developments is presented. The aim is to avoid over - as well as under-exploitation of data. |

5. shows the resolution function for five different values of the nominal scattering

vector. At low (q) the resolution function is dominated by the contribution from the

spread in

wavelength spread at high (q). 3. Small-angle X-ray scattering instruments In

SAXS, the combination of very intense incident beams and imperfections of the

slits or pinholes leads to a significant parasitic scattering from the slits or pinholes
