摘要：

We study collective diffusion in a semidilute suspension of Brownian particles interacting with a square well potential. Under neglect of hydrodynamic interactions, we derive an explicit expression for the wave number- and frequency-dependent diffusion coefficient. At zero frequency, the diffusion coefficient exhibits a resonance structure which varies strongly with the square well parameters.
