19. We estimate the uncertainty of our D values (spheres in Fig. 3) to be less than ± 50% even at the lowest temperatures. D values from the pulsed gradient technique used in Ref. 16 can be increased by systematic errors, in particular, in the limit of slow diffusion. Therefore, we believe that the upturn of the triangles in Fig. 3(b) is an artifact.
