X-ray and Neutron scattering FYS620

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.

The course has a continuous assessment. All parts must be passed in order to obtain a final grade.A re-sit exam is offered for the oral exam in accordance with the faculty's ordinary cycle.There is no re-take possibilities for the laboratory report. Students who wish to improve their grade on this part may do so the next time the course is lectured.
