Neutron Scattering as a Powerful Tool for Studying Multi-Scale Structure for Planetary Sciences

Neutrons can be used as a powerful probe and vital tool for a wide range of scientific and industrial fields. Neutron scattering is used to obtain a direct and detailed insight into the structure and dynamics of condensed matter – matching dimensions in space from single atoms to macromolecules and in time from atomic vibrations to diffusion of large molecular units – depending on the instrument and facility used. Compared to other scattering probes, neutrons are non-interacting and scatter off the nucleus – allowing for much deeper penetration. This unique mechanism gives them the ability to ‘see’ hydrogen with high sensitivity, which is present in most molecules relevant to planetary and interstellar environments, and allows them to differentiate between isotopes.

By exploiting isotopic differentiation, such as using selective H/D substitution, we can also highlight interatomic correlations of interest. Another important advantage is that complex sample environments can be used, such as in situ vacuum chambers, pressure, and flow cells.

In this webinar, Zachary Amato will present each of the main techniques (diffraction, small-angle, dynamics, spectroscopy, and imaging) and go through examples of studies relevant to planetary sciences.
