Abstract
We analyze a set of small-angle neutron scattering (SANS) data of micellar solutions using a re- scaled mean spherical approximation (MSA). The rescaling is shown to overcome the inaccuracy of MSA for the cases of dilute and strongly coupled solutions. The theory is in excellent agreement with SANS data for dilute as well as concentrated solutions. The counter-ion size effect is explicitly taken into account and the extracted renormalized micellar charges are reasonable but smaller, compared to that from the rescaled one-component macro-ion approximation.
