Abstract
The dynamics of positron-electron correlated pairs (positronium, Ps) i n aqueous solutions of sodium dodecylsulfate and dodecyltrimethylammon ium bromide at different concentrations was investigated by means of l ifetime spectroscopy at room temperature. The results were framed with in a simple trapping model; separate magnetic quenching experiments su pplied information on the site of Ps trapped inside the micelles. From the lifetime data an estimation of the surface tension inside the mic elle was obtained.
