We report the results of theoretical and experimental
investigation of spin diffusion in the normal phase of liquid 3He
confined in planar aerogel: a material consisting of nanostrands which
are almost parallel to a specific plane and randomly oriented in this
plane. Using spin echo technique we measure the spin diffusion
coefficients in the directions perpendicular and parallel to the plane.
We see good agreement between the experiment and the theory.
