Investigation of hydrogenous materials using neutrons

Slow neutrons have proved to be a very powerful probe for examining materials in general and hydrogenous materials in particular. In this article, various neutron scattering techniques which have been utilised to investigate different aspects of a variety of hydrogenous materials have been reviewed. Translationally as well as orientationally disordered materials, ferroelectrics, superconductors, metal-hydrogen systems, polymers and biological molecules have been chosen as illustrative examples.
