Neutrons as a sensitive tool to investigate nano- and mesostructured materials — •Stephan Förster — University of Bayreuth, Fakultät für Chemie

Neutrons can be similarly used as x-rays to investigate the structure of nano- and mesoscale synthetic and biological materials. Since, compared to photons, neutrons posses a spin, penetrate deeper into materials, and because the neutron-scattering cross-sections can vary strongly for different isotopes of the same element, they are a much more sensitive and versatile tool.

In the tutorial the basic experiments that can be performed with neutrons, in particular neutron scattering, are described and a number of examples from material and life science are given for illustration. The tutorial also includes practical hints for the application of beam time at neutron facilities.
