A simple model of a dry reversed micelle of ionic surfactants is proposed, according to which during the
optimization procedures the ions move over certain closed surfaces in a vacuum at T = 0 K .The electrostatic
interactions of discrete ions in dry, reversed micelles of AOT are calculated as a function of the sizes of the
ions, ion charges, and the optimum positions of the ions in the polar cavity of the micelles. It is shown that
when the counterions penetrate the layer of the potential-determining ions, the electrostatic interaction begins
to favor the self-organization of the ionic surfactants over that of the reversed micelles. The distribution of
the electrostatic potential in the polar cavity of micelles of different shapes (a sphere, a spheroid, a prolate
ellipsoid) is calculated. In the models in which the charge is taken to be discrete, the electrostatic field
extends beyond the double electric layer (DEL); the sign of the potential coincides with that of the counterion.
It is shown that in the analysis of structures of dry, reversed micelles the possibility of the formation of voids
(in the surface layer of polar groups and in the center) as well as the density of packing should be taken into
account by using a specially developed approach. The most probable structural parameters of AOT micelles
are determined for different counterions (Li+, Na+, Cs+, [Co(H2O)6]2+, La3+).
