Neutron scattering is a powerful non-destructive analytical technique that is used to investigate the structure and dynamics of materials at the atomic and molecular level. Neutrons are subatomic particles that have no electric charge, and they interact with matter through the strong nuclear force. This makes them ideal for probing the structure of materials, as they can penetrate deeply into materials without being significantly scattered by electrons.
Neutron scattering experiments are typically performed using a neutron source, such as a nuclear reactor or a spallation neutron source. The neutrons are then directed onto the sample, and the scattered neutrons are detected and analyzed. The scattering pattern contains information about the structure and dynamics of the sample, and it can be used to determine a variety of properties, such as the atomic structure, the vibrational modes, and the magnetic properties of the material.
Neutron scattering is a versatile technique that can be used to investigate a wide range of materials, including solids, liquids, and gases. It is a powerful tool for understanding the structure and dynamics of materials, and it has applications in a variety of fields, such as materials science, chemistry, biology, and physics.
