Neutron spectroscopy on solids — •Astrid Schneidewind — Helmholtz-Zentrum Berlin für Materialien und Energie

Neutron scattering is an outstanding and often a unique technique to study the dynamic properties of solids on an atomic scale. The tutorial will give an overview about the opportunities and the constraints of the method. Coming from the understanding of the properties of the neutron and the lattice, the nuclear and magnetic cross-sections for the interaction of the neutron with the lattice will be shown. Typical problems and the results of the required measurements will be presented and used to illustrate the aspects of the different techniques, with focus on three axis spectroscopy and time-of-flight methods. The specific role of neutron scattering in studies on magnetism will be accentuated. Finally, the complementarities to other methods as Raman and infrared spectroscopy, NMR and X-ray scattering will be pointed out.
