On quasi-elastic scattering of slow neutrons in molecular liquids

The rotational broadened quasi-elastic scattering spectrum of neutrons in a molecular liquid which is studied in the framework of the step formalism and the rotational diffusion approximation can be decomposed into simple Lorentzian distributions. The possibility of separately observing these terms in the experiment is discussed with respect to the numerical results of their energy broadening and amplitude for the case of liquid benzene.
