Dressed-ion theory

The fundamental theories on EDL interactions have been substantially advanced by several researchers in the recent past in order to incorporate the effects of other pertinent physicochemical phenomena in the mathematical model and to generalize the underlying postulates. Kjellander and Mitchell [5] employed the dressed ion theory for EDL structure and interactions, which is nothing but an exact statistical mechanical formahsm for electrolyte systems. In their theory, the dressed ions took equivalent roles as the bare ions in the Poisson-Boltzmann approximation. A practical method was also derived for evaluating the effective surface charge densities of the particles. Behrens and Borkovec [6] proposed...

There have been other attempts to apply integral equations methods derived from Equation 3.51 or other similar expressions. One of them is the hypemetted chain (Henderson 1983), which is a generalization of the MSA theory, applicable to higher charge/potential values. It gives results comparable to the MPB ones but requires more extensive numerical evaluations. Another proposal is so-called dressed-ion theory of Kjellander and Mitchell (1994, 1997).

This shows that although the th ion is treated with a finite radius, all others are considered as point ions. The obvious remedy, which can also be justified on statistical mechanical grounds according to dressed-ion theory is to replace Eq. [355] with the symmetric relation...

As we have seen, the spectra of electrons ejected from a target atom or molecule by dressed ions and neutrals are quite different from those induced by bare projectiles. These differences cannot be explained by use of a simple effective charge as was defined by stropping power theory. For fast relatively simple dressed ions, such as H° or He, the separation of target and projectile ionization is relatively straightforward. The single...
