Abstract
The relative-angle distributions of IMFs, studied for the system alpha +Au-197 at 3.6 GeV/nucleon, show a strong suppression of small relativ e angles. By multi-body Coulomb trajectory calculations it is shown th at the magnitude of this effect is very sensitive to the time scale of the IMF emission. The experimental angular distributions are well des cribed assuming a fast breakup of the system with times less than 100 fm/c between IMF emissions.
