Correlated dynamics and light scattering in microemulsions

Abstract

An interpretation is given to the wavenumber-dependent effective diffusion coefficient extracted from the scattered light spectra of a microemulsion system. At high concentrations of suspension this diffusion coefficient shows a minimum in its variation with wavenumber in a region well below the diffraction maximum in the static structure factor. The interpretation is based on an analogy with the Lorentz model, where particles diffuse in a random, static medium. Since a similar wavenumber variation is also found in the Lorentz problem, it is suggested that this behaviour is characteristic of correlated dynamical interactions between the diffusing particle and a structureless but dense medium. © 1982 Taylor & Francis Group, LLC.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
