What is neutron scattering?

“Neutron scattering” is one of the best methods to study the properties of materials in today. Various materials such as superconductor, magnetic material, high-molecular and biological substance are investigated using neutron beam generated from research reactor or accelerator. Neutron, an elemental particle constructing materials, which has an excellent permeability and a property of the minimum unit of magnet, i.e. spin, interacts with nucleus at the center of the atom and magnetic field (or magnetic moment) induced by electrons around the core. Based on these properties, we obtain atomic and magnetic structure of materials and their dynamical properties, by exposing many neutrons to such a material and measuring scattering direction, velocity and spin direction or its vibration. Neutron scattering is useful from the viewpoint of how the character and function of these materials connect with the underlying atomic and molecular arrangement and their movement, as the most powerful experimental method in various fields such as physics, chemistry and biology from basic to applied research area.
