Measurement of absolute intensities allowed to determine unambiguously normalized values of S(q). With decreasing volume fraction, the amplitude of the first peak of S(q) reflecting the order of the suspension does not monotonically decrease, but rather shows a distinct minimum at φ ∼ (5−8)×10­ˉ³. This reappearance of structure is compared with theoretical predictions on the basis of a jellium model for the effective interparticle potential Ueff (r).</dcterms:abstract> <dc:creator>Urban, Claus</dc:creator> <dcterms:title>Reappearance of structure in colloidal suspensions</dcterms:title> <dcterms:rights rdf:resource=""/> <dc:contributor>Rojas, L.
