Quasielastic scattering
In physics, quasielastic scattering designates a limiting case of inelastic scattering, characterized by energy transfers being small compared to the incident energy of the scattered particles.
The term was originally coined in nuclear physics.[1]
It was applied to thermal neutron scattering by Leon van Hove[2] and Pierre Gilles de Gennes[3] (quasielastic neutron scattering, QENS).
Finally, it is sometimes used for dynamic light scattering (also known by the more expressive term photon correlation spectroscopy).
