This is the study programme for 2020/2021.


Introduction to X-ray and Neutron scattering. The course covers the basic physical principles underlying the interaction of X-ray 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 be able to explain various types of interactions between x-ray/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 X-ray scattering is a suitable experimental technique for a given project. Explain the structure of instruments for the different types of experiments.
