[en] For sufficiently energetic collisions between heavy ions, a number of theoretical studies predict the existence of a multifragmentation process where the system disintegrates into massive and numerous fragments. What is particularly disturbing is that the approaches use very different assumptions ranging from transition between liquid-gas phases, cold break-up, statistical decay of hot nuclei to simple consideration of the available phase-space and yet are to a large extent, capable to represent the data reasonably well. We have set an objective to perform measurements where it might be possible to choose between the different mechanisms. In this contribution we report on preliminary results on the reactions Ne+Au and Ne+Ag at 60 MeV/A using the Neon beam provided by the GANIL facility
