We find that the superdiffusivity, which is characterized by the superdiffusion parameter $\\alpha$, impacts significantly the distribution of CRs. For impulsive injection, the CR distribution behaves a constant radial profile, except with a power-law tail for $\\alpha < 2$ or a Gaussian tail for $\\alpha=2$ at large distance, $r$, from the accelerators.
