Abstract
We study the scattering properties of a polymer gel uniaxially deforme d by anisotropic swelling. Both the light- and neutron-scattering inte nsities appear to be greatly enhanced along the direction of maximum d ilation, Using a scanning light-scattering device, we show that this e ffect is governed by the ''quasistatic'' fluctuations, in space, of th e polymer concentration, and not by the ''thermal'' fluctuations.
