Abstract: The random diffusion model is a continuum model for a conserved scalar density field ϕ driven by diffusive dynamics where the bare diffusion coefficient is density dependent. We generalize the model from one with a sharp wave-number cutoff to one with a more natural large wave-number cutoff. We investigate whether the features seen previously--namely, a slowing down of the system and the development of a prepeak in the dynamic structure factor at a wave number below the first structure peak--survive in this model. A method for extracting information about a hidden prepeak in experimental data is presented.
