Abstract
Until now, it has been observed that a collective handling of uniform spheres could only lead to a random close packing of 0.64 maximum volu me fraction. In this Letter, we show that denser crystalline arrangeme nts can be obtained when beads are poured at low flow rates into a hor izontally shaken container. A parallel is suggested between this proce ss and that of colloidal sedimentation which also yields crystalline s tructure. [S0031-9007(97)04421-9].
