FLUCTUATING INTERFACES IN MICROEMULSION AND SPONGE PHASES - REPLY

In reply to the preceding Comment of Pieruschka, Safran, and Marcelja, we show that the scattering intensity of level surfaces of Gaussian random fields has the same asymptotic behavior for small wave vectors, both for interfaces of constant and of fluctuating thickness. In the former case, Monte Carlo simulation results for the film correlation function in a Ginzburg-Landau model are found to be in very good agreement with variational results; in particular, the oscillatory component of the correlation function is found to be much more pronounced than for interfaces of fluctuating thickness.
