(a) Atom distribution of CeO2 in real space, and a sphere centered at an atom with radius r and annulus thickness dr.[11] (b) High-energy x-ray total scattering derived pair distribution function in real space, G(r), provides real-space structure information which is independent of structure modeling.[39]
