Use of perturbed angular correlation technique for studies of equilibrium systems: Cd-ions in water-pools of reversed micelles

Possibilities and limitations of the perturbed angular correlation technique were investigated in a study of water-pools of reversed micelles of sodium-diethylhexylsulphosuccinate in iso-octane. Probe nuclide for the measurements was reactor produced 111mCd in the form of Cd2+-ions. The results indicate that Cd2+-ions are present inside the water-pool and predominantly experience the movements of the surrounding H2O molecules. An increase in the average number of Cd2+-ions per micelle seemed to have consequences for the size of the pools and, consequently, of the reversed micelles. (author)
