Abstract :
Events in which at least 5 fragments with charge larger than 8 were emitted in dissipative Pb + Au collisions at 29 MeV/u incident energy are studied. An event by event shape analysis is performed and a prescription is proposed to select the most central collisions. For these latter, it is shown by comparing the data with the results of computer simulations that the di-nuclear system disassembles before re-separating, meaning that its lifetime is smaller than the interaction time. This conclusion is also supported qualitatively by studying light particle patterns.
