Scattering from Fluids of Nonspherical Molecules. I. X Rays and Neutrons

摘要

The general theory of the statistical mechanics of nonspherical molecules is applied to the problem of the scattering of x rays and slow neutrons from a fluid composed of nonspherical molecules. Expressions for the differential scattering cross sections are derived for the cases of both elastic and inelastic scattering. General properties of the timehyphen;dependent correlation functions are discussed, and a shorthyphen;time approximation is given and applied to the calculation of the inelastic neutron scattering cross section.
