Abstract

In this paper we evaluate the distribution of ions around a charged cylinder, in thermal equilibrium, taking into account the main effects of the excluded volume of the counterions. The cylinder is a model of a DNA molecule. There are major corrections to the standard Gouy-Chapman theory when the electrostatic energy due to the charge of the cylinder is large as compared to the thermal energy. The concentration shows a distinct saturation effect over a finite region, which may be interpreted as the Stern layer of immobilized ions. The known saturation of the electrostatic potential at the surface of the cylinder is removed.
