Abstract :
Ripplon light scattering technique was applied for the investigation of the mechanical properties of the surface of surfactant solution. The velocity and damping constant of the ripplon were measured for decyl-alcohol solution under periodical modulation of the surface area and the dynamic surface tension was obtained in the frequency range of 10-3-10-1 Hz. The relaxation of surface elasticity due to the adsorption and desorption of the surfactant molecules was successfully observed
