Orientational Dependence of the Self-Diffusion Tensor and Relaxation-Time Spectra for Nematic Phase of Hard Ellipsoid Particles
The tensors of friction coefficients and relaxation times are calculated in the Enskog approximation at fixed orientation of a target particle. The angular dependence of the latter makes possible to introduce the velocity relaxation time spectra. So the Enskog theory originally operating with a single relaxation time allows to incorporate the whole spectrum when the selfdiffusion coefficients are considered.
