(a) The self-diffusion coefficients DS of colloidal particles as a function of interparticle distance X, (b) rescaled diffusivities ( D S − D S 0 ′ ) / ( D S 0 − D S 0 ′ ) as a function of X / 2 a . Symbol colors and shapes correspond to various p values. The horizontal lines mark D S 0 and vertical lines mark X.
