Introduction to Xray and Neutron scattering. The course covers the basic physical principles underlying the interaction of Xray and neutrons with matter, as well as the physics behind standard experimental techniques used to understand the structure and dynamical processes in matter.
Learning outcome
After completing the course, the student will have an understanding of the spatial structure of simple crystals as well as explain the correlation between the reciprocal lattice, miller index and diffraction. Be able to explain various types of interactions between xray/neutrons and matter. Characterize main types of scattering: elastic / inelastic, coherent / incoherent, nuclear / magnetic, apply the theory of basic principles in diffraction and spectroscopy. Be able to calculate structural factors for simple systems. Be able to explain fundamental characteristics of synchrotron radiation as well as various types of experimental methods associated with the use of neutrons and synchrotron radiation. Determine whether neutron scattering or Xray scattering is a suitable experimental technique for a given project. Explain the structure of instruments for the above types of experiments.
