Incoherent scattering law for neutron quasi-elastic scattering in liquid crystals

Abstract

The incoherent scattering law for neutron quasi-elastic scattering in liquid crystals is calculated using a classical formalism including (anisotropic) self-diffusion, rotational motion along the long molecular axis and short time vibrational behaviour. Explicit expressions are given for oriented as well as for unoriented liquid crystals.
