Abstract
As a test of the modified Mori theory of Joslin and Gray [1], we calculate the diffusion coefficient, D, for a dilute gas of hard spheres. Using the frequency moments of the velocity autocorrelation function as input, the theory yields a sequence of successive approximations D (2), D (3), …, etc., where D (n) is based on moments M 0, M 2, …, M 2n . We find that this sequence converges rapidly to a limit within about 1 per cent of the true value of D.Keywords
