  Numerical 1D-3V solutions of the Wong-Yang-Mills equations with anisotropic
particle momentum distributions are presented. They confirm the existence of
plasma instabilities for weak initial fields and their saturation at a level
where the particle motion is affected, similar to Abelian plasmas. The
isotropization of the particle momenta by strong random fields is shown
explicitly, as well as their nearly exponential distribution up to a typical
hard scale, which arises from scattering off field fluctuations. By variation
of the lattice spacing we show that the effects described here are independent
of the UV field modes near the end of the Brioullin zone.
