22. The micelle in the center contributes as a whole micelle, each of the 8 micelles in the corners contribute 1/8, and each of the 12 micelles at the faces contribute 1/2 to the unit cell.
23. -3 it can be calculated that each cubic unit cell contains about 350 molecules.
24. A value of 1.35:1 was obtained by fluorescence quenching experiments of normal cubic mesophases of lyotropic systems (type 1): L. B.-A. Johansson, O. Söderman, J. Phys. Chem. 1987, 91, 5275.
25. Two different kinds of micelles were found: spherical and tetrahedral distorted.
