The charge structure function in electrolytes and polyelectrolytes.
The relation between charge and dielectric structure functions is examined in the case of electrolytes and polyelectrolytes. When the coupling constant is larger than unity, characteristic features should be observed on the dielectric structure function, in addition to the classical screening effect. We point our the existence of experimental conditions which provide direct information of the dielectric structure at shorter wavelength (lambda 1 nm). They correspond to zero average contrast in scattering experiments.
