• Diffusion of electrons in three-dinaensional disordered systetaas is investigated numerically forall three universality classes, namely, orthogonal, unitary and symplectic ensembles. The secondmoment of the wave packet (r'(Z)) at the Anderson t.ransition is shown to behave as xt'(a ':2/3). From the temporal atrtocorreJation function C(t), the fractal dimension D) is dedvrced,which is alunost half the value of the space ditnension for all of the vrniversality classes.
