Abstract

Thin soap films drawn from concentrated surfactant solutions show stepwise thinning due to micellar organization into layers. We study by light scattering methods the extent of order as a function of surfactant concentration and show that the behavior of the micelles in the confining geometry of the film is analogous to that of ordinary fluids confined between walls. Our results compare very well with predictions of a recent model for density oscillations in liquids, supplemented by a calculation of bulk properties based on the rescaled mean spherical approximation.
