✦ Synopsis

To investigate the approach to the asymptotic long time behaviour in a d-dimensional Lorentz gas, we have calculated the ~7(t -2-dj2) correction to the long time tail t -1-d/2 in the velocity autocorrelation function, using low density kinetic theory. The results are compared with existing computer simulations.
