The Macroscopic Liquid-Drop Collisions Project: A Progress Report
In previous workshops of this series we presented results of the fragmentation observed in collisions of equal-size mercury-drop pairs, and a comparison of these data with predictions of a dynamic nuclear reaction model, modified to allow the simulation of macroscopic liquid-drop collisions. In the last presentation we also showed preliminary results of an experiment designed to investigate the formation of “exotic shapes” (sheets and donuts) predicted to occur in heavy-ion collisions. The motivation for this seemingly wayward approach, of hoping to learn something about nuclear dynamics from what is observed in macroscopic liquid-drop collisions, can be found in the written versions of our previous presentations. Here we give a progress report on two subjects. The first is a study of the evolution of the surface shape of a system composed by two, equal-size, drops put in contact at the lowest possible relative velocity. The second is related to a qualitative description of the instabilities of the exotic shapes reported previously in central collisions of equal-size drops.
