We have studied the sponge phase (L3) of binary mixture of C12E5 and water by the dynamic light scattering technique. At the concentration above 2w%, an almost single relaxation related with the cooparative diffusion of membranes is detected. The dynamic correlation lengh is evaluated from the diffusion constant to be a little larger than that obtained for the Lα phase. At the concentration below 2w%, we can find the crossover behavior Γ∝q2 to Γ∝q3 in the dispersion relation between the inverse correlation time Γ and the scattering wavenumber q.
