Abstract A numerical test is made of the Gaussian approximation to the Fokker-Planck equation for a Hamiltonian with two degrees of freedom and potentials and friction coefficients appropriate for the description of the deep inelastic collision of the system40Ar+232Th atE lab=279 MeV. The exact solution is constructed with the Langevin's simulation method. The failure of the gaussian approximation is discussed and we exhibit separately its sources from (i) diffusion coefficients, the linearization (ii) of the potentials and (iii) of the friction forces.
