Description:
This lecture introduces the neutron diffraction method as the method used in solid state physics research and the materials sciences. The basic principles of the nuclear and magnetic neutron scattering are given, as well as the comparative properties to the X-ray method. The basic concept of this method is illustrated by many practical examples.
