Annotation
The course describes diffraction methods and the procedures for their processing as used in mineralogy. The possibilities and limitations of certain experimental techniques are explained. Also, real structure influence on the diffraction patterns is addressed.
Due to the pandemic situation, the course in the summer semester of the academic year 2020/2021 takes place in a combined online form and self-study of provided selected literature. Information on how to connect to an online lecture will be provided to enrolled students via e-mail.
