Outline of neutron scattering formalism

Outline of Neutron Scattering Formalism

Neutron scattering formalism is briefly surveyed. Topics touched upon include coherent and incoherent scattering, bound and free cross-sections, the Van Hove formalism, magnetic scattering, elastic scattering, the static approximation, sum rules, small angle scattering, inelastic scattering, thermal diffuse scattering, quasielastic scattering, and neutron optics.

Formalism for obtaining nuclear momentum distributions by the Deep Inelastic Neutron Scattering technique

We present a new formalism to obtain momentum distributions in condensed matter from Neutron Compton Profiles measured by the Deep Inelastic Neutron Scattering technique. The formalism describes exactly the Neutron Compton Profiles as an integral in the momentum variable y. As a result we obtain a Volterra equation of the first kind that relates the experimentally measured magnitude with the mo...

Small angle neutron scattering

Small Angle Neutron Scattering (SANS) is a technique that enables to probe the 3-D structure of materials on a typical size range lying from ∼ 1 nm up to ∼ a few 100 nm, the obtained information being statistically averaged on a sample whose volume is ∼ 1 cm3. This very rich technique enables to make a full structural characterization of a given object of nanometric dimensions (radius of gyrati...

Neutron Scattering Technique

Neutron scattering technique is the most modern method of sampling the dynamics and structural properties of molecular systems. Neutrons interact with atoms via nuclear which has nuclear forces that are very short ranged. For this reason, neutrons can better penetrate into sample matter and obtain the information that would have been able to by other methods, such as x-rays. In this paper, we s...
