Neutron diffraction

Neutron diffraction is a powerful and often unique tool for studying the structure of objects used in everyday life. It is in fact a very precise technique for measuring the structure of crystalline materials, ranging from the simplest to the most complex.

Small-angle neutron scattering (SANS)

Small-angle scattering does not attempt to see atoms but is interested in the organisation of particles in dispersed systems. As scattering elements are large (grains, bubbles, micelles,..), diffraction occurs at very small angles.

Inelastic neutron scattering (INS)

To understand the properties of materials it is also necessary to have knowledge of how the atoms and molecules vibrate, rotate and move within the medium. Inelastic neutron scattering is an excellent means of studying these movements.
