Query: Multifragment production in Au+Au at 35 MeV/u   Multifragment disintegration has been measured with a high efficiency
detection system for the reaction $Au + Au$ at $E/A = 35\ MeV$. From the event
shape analysis and the comparison with the predictions of a many-body
trajectories calculation the data, for central collisions, are compatible with
a fast emission from a unique fragment source.
