AOT is also known to be very sensitive to the concentration and nature of counter-ions. When adding a sufficient amount of divalent salt to an AOT solution, a very strong Bragg peak appear at Q=0.2A-1 which is not seen in the salt free system. The first focus of this investigation is to explore the nature of the structure associated with this Bragg peak. It is thought to arise from the collapse of the multilayer that originally forms at the surface. A second aim is to study the kinetics of rinsing of the multilayers to study how they are removed both from the hydrated (no salt) and dehydrated (Calcium) solutions.
