Abstract
We demonstrate that, at low shear rates, the scattering peak in the st ructure factor of sheared polymer solutions results from the combined effects of advection and flow-induced concentration fluctuation enhanc ement. Using time-resolved small angle light scattering, the distance of the peak from the origin of the reciprocal space is shown to scale as gamma(1/2), where gamma is the shear rate of the flow.
