• Diffusion processes
• algebraic convergence
• classical coupling
• coupling by reflection
• spherically invariant

We consider the diffusion process X (t) on a"e (n) with radial diffusion and drift coefficients. We prove that once the one-dimensional diffusion |X (t) | has algebraic L (2)-convergence, so does X (t) . And some classical examples are discussed.
