Show affiliationsNeck formation and fluctuating neck scission in deep-inelastic collisions (DIC) of heavy nuclei are studied. Assuming the applicability of hydrodynamics to gross nuclear reactions, the authors find that a hydrodynamic instability governs the exit channel of the reaction. This suggests a new model, random neck rupture, for DIC. It explains the observation of almost no mean mass shift despite the extremely large variances of the fragments produced. Random neck rupture relates the mass variances to the energy losses and thus establishes an extended Viola systematics. The origin of the lead-uranium anomaly is discussed. They propose the use of alpha -particle multiplicity experiments to measure the size of the neck.
