Abstract
The effect of persistent correlations on self-diffusion in a dilute gas, and on Brownian motion, is discussed. It is found in both cases that the second-order diffusion constant is infinite. The distribution function for displacements is calculated, and is found to be more sharply peaked than the usual Gaussian, although the difference is quite small.Keywords
