Dynamics of caged microemulsion droplets: a neutron spin echo and dynamic light scattering study (original) (raw)

Physica B: Condensed Matter, 2004

Abstract

We report a neutron spin echo (NSE) and dynamic light scattering (DLS) study of droplet dynamics in a microemulsion at high droplet packing fraction (Φdroplet∼62%). NSE measurements in range qr⪢1 allow to investigate the short-range Brownian motion of droplets trapped within the cages formed by their nearest neighbors. For a particular scattering contrast, NSE also reveals, for q values around
