Computed from the area of the energy hypersurface where these events take place, the probability for (DeD) near-collisions is many orders of magnitude above the probability for tunneling through the Coulomb barrier in a (DeD)<jats:sup>+<\/jats:sup> bound state, when e is a light particle. <\/jats:p><jats:p> If the Coulomb system is embedded in a metallic lattice, access to the near-collision regions in the phase space is hindered by the regularity of the lattice. One should then expect, at most, intermittent and irreproducible behavior associated to mechanisms like Arnold\u2019s diffusion. Mechanisms to restore ergodicity are proposed. <\/jats:p><jats:p> Numerical simulations are performed on a three-body system to compare the observed rate of near-collisions in actual orbits (with random initial conditions) with the phase-space estimates. It is found that local conservation of angular momentum causes large deviations from the phase-space estimates. <\/jats:p>","DOI":"10.1142\/s0217984993001958","type":"journal-article","created":{"date-parts":[[2004,11,19]],"date-time":"2004-11-19T12:08:05Z","timestamp":1100866085000},"page":"1929-1939","source":"Crossref","is-referenced-by-count":0,"title":["NEAR-COLLISIONS IN A COULOMB SYSTEM: NUMERICAL SIMULATIONS \u2014 A PRELUDE TO HYBRID FUSION"],"prefix":"10.1142","volume":"07","author":[{"given":"R.
