Inelastic Neutron Scattering from Structural Excitations
In this lecture, a short overview is given over the characteristic features of inelastic neutron scattering along with some selected applications for the investigation of dynamic processes in condensed matter. Of course, a comprehensive treatment of the entire field of neutron scattering cannot be provided within a single lecture. Hence, I restricted myself on the treatment of structural excitations thereby skipping the important field of magnetic excitations. After some introductory remarks about the role of neutrons in condensed matter research, a brief summary of scattering processes and correlations will be given along with a short review on experimental techniques. The potential of inelastic neutron scattering will be demonstrated with the help of a number of different examples dealing with collective excitations, diffusion processes, tunnelling, polymer dynamics, and kinetic studies. More detailed information about individual aspects of different applications and techniques may be found in the series of lecture notes of summer schools organised by FZ Jülich or PSI, Villigen .
