Neutron techniques encompass a group of experimental methods that use beams of thermal, cold, or fast neutrons to probe the structure, dynamics, and magnetic properties of materials at atomic to mesoscopic length scales. Principal methods include neutron diffraction for crystallographic and magnetic structure determination, small-angle neutron scattering (SANS) for studying nanoscale inhomogeneities, and inelastic or quasielastic neutron scattering for characterizing lattice vibrations, molecular motions, and spin excitations. These techniques exploit the neutron’s charge neutrality, nuclear-specific scattering cross sections, and magnetic moment, enabling high sensitivity to light elements, isotopic contrast variation, and direct measurement of magnetic correlations in condensed-matter, soft-matter, and biological systems.
New research in quantum entanglement could vastly improve disease detection, such as for cancer and Alzheimer's disease.
