Data for: Structure of self-assembly amphiphilic systems: relation between phenomenological parameters and microscopic potential parameters

The correlation and structural functions of symmetric amphiphilic systems are studied. The systems are modelled by a double Kac potential and analyzed analytically with the thermodynamic perturbation theory relatively to the hardsphere reference system. The microscopic approximation applied to the model yields a theory consistent with the phenomenological Landau-Ginzburg theory of microemulsions.
