Abstract
The repeated-ring kinetic equations are accurately solved for the velocity-correlation function of a tagged particle in a three-dimensional Lorentz gas. Analytical expressions for the long-time behavior and for both the low- and high-density limits of the diffusion constant, calculated within the repeated-ring approximation, are also presented.Keywords
