Abstract
Applicability of the mean spherical approximation (MSA) and hypernetted-chain approximation (HNCA) to the analysis of intermicellar structure factors was examined. For a strongly coupled micelle-counterion system at high volume fraction the MSA partial structure factors are close to the corresponding HNCA solutions provided the micellar charge is appropriately reduced in the case of MSA. The same agreement for the micelle-micelle structure factor can still be maintained at low volume fraction by using the previously proposed rescaled MSA. In certain cases, the experimental intermicellar structure factor can be satisfactorily reproduced within the HNCA by assuming the micellar charge to be substantially lower than the mean aggregation number of the micelle.
