Abstract
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 time‐dependent correlation functions are discussed, and a short‐time approximation is given and applied to the calculation of the inelastic neutron scattering cross section.
