Small-angle neutron scattering is an experimental technique that uses elastic neutron scattering at small scattering angles to investigate the structure of various substances at a mesoscopic scale of about 1–100 nm. Small angle neutron scattering is in many respects very similar to small-angle X-ray scattering; both techniques are jointly referred to as small-angle scattering. Advantages of SANS over SAXS are …

Neutron scattering refers to the dispersal of free neutrons by a neutron source, such as californium-252. While the process occurs naturally, it can also be used in experimental operations to determine the composition and structural characteristics of a material.

Using inelastic neutron scattering would allow him to collect data on the dynamics, or the motions, of an HIV protease, which would add to the neutron diffraction data he’d been collecting for years. Neutron scattering techniques, such as neutron diffraction or neutron radiography, evolved over more than four decades at user facilities and have unique advantages for characterization of nuclear materials: (i) Neutrons penetrate many materials to depths of several centimeters, hence allowing to use shielding or preventing the removal of the cladding material for characterization of, for Neutron scattering is one of the most important experimental methods for the study of the atomic-scale structure and dynamics of condensed matter. Neutron scattering complements the well-known technique of X-ray diffraction by being well suited for the study of light elements (hydrogen in particular), magnetic structures, and collective excitations like lattice vibrations and spin waves.

Neutron scattering is a non-invasive method of observing and analyzing the structure and nature of a variety of materials. By using neutron sources with varying levels of radiation intensity, researchers can attain a deeper understanding of the physical and chemical properties of materials.

Since this introduction is exactly that, the reader is encouraged to look to the extensive literature on the subject and a recommended reading list is provided at the end. Much of the material presented here has been adapted from those references.
