Abstract
We study recent measurements of Ar+Mo reactions. Transport models do not agree with the data for large energy losses; they predict too small fluctuations and too much drift. Random neck rupture is however in keeping with experiments. We explain random neck rupture by very simple analysis and show that its basic ingredient, the critical ratio of total length over neck radius, is largely independent of angular momentum. We propose experiments to examine random rupture, one of them, a neutron multiplicity experiment, with a prediction of a saw-tooth structure.
