It is proposed to make a numerical study, both classically              and quantum mechanically, of the stability of distorted Coulomb                 orbits under the influence of stochastic perturbations.  The                    primary goal of the investigation is the study of the atomic                    dynamics under the influence of strong noise.  The method we                    will use is the numerical Monte-Carlo solution of a classical                   Langevin equation and the solution of a quantum master equation                 for the reduced atomic density matrix.  The comparison between                  the classical and the quantum treatment should provide novel                    information on the degree of suppression of indeterministic                     (stochastic) diffusion due to discreteness effects of quantum                   states.  Applications will focus on the dynamical evolution of                  excited states of fast atomic particles penetrating solids                      under the combined influence of stochastic collision processes                  and dynamical screening in the many-body target.
