Our result implies that characterization techniques based on scattering of dilute particulate streams cannot be extended to high density. This calls into question recent efforts to interpret collimation in the scattering pattern generated by gold-ion collisions at the Relativistic Heavy Ion Collider as evidence for a liquid phase in the quark-gluon plasma. Second, an interior dead zone with highly collimated ejecta have also been observed in impact experiments using cohesive silica aggregates. This regime of impact sheds light on the formation of planetesimals. Thus our results may provide a framework for thinking about impact in the more complex circumstances that arise for impact in granular materials as well as foams, emulsions and dense suspensions.
