We present a numerical study of a Langevin-equation model for a simple fluid. We study the relaxation kinetics of the density-time-correlation function. We find a stretched exponential regime with an exponent β depending on wave vector in agreement with results obtained from mode-coupling theory and correlated with the wave-number dependence of the static-structure factor. At larger wave vectors, we find a transition to power-law behavior after a rapid decay.
