| We demonstrate that aqueous solutions of giant polymer-like non-ionic micelles `doped' with small amounts of ionic surfactants serve as ideal model systems for `equilibrium polyelectrolytes'. We report systematic light and neutron scattering investigations of the effect of ionic strength, total concentration and doping level on the static properties of dilute and semi-dilute micellar solutions. In dilute solutions we observe a dramatic influence of (intramicellar) electrostatic interactions on the micellar flexibility, and the results are in close agreement with Monte Carlo simulations. In the semi-dilute regime, strong long-range interactions between micelles induce liquid-like ordering.
