Abstract: Using the kinetic methods of the Brussels school, we establish the equation (to the second order in the perturbation) for the return to equilibrium of the one-particle energy distribution function in the nematic phase of a fluid made of thin slabs interacting through a P2-type potential. On the basis of the mean field equilibrium theory developed by Maier and Saupe for such a fluid, we show that for a very heavy brownian particle, this equation reduces to a Fokker-Planck type equation; the friction coefficient thus obtained is compared with the friction coefficient obtained for the isotropic phase and we show that they are equal for the transition temperature.
