Figure 2
Raw Fourier synthesis [equation (3)] of the ED distribution for CaB6 at [sin(θ)/λ]max = 1.5 Å−1 shown in the (200) and (110) planes. (a) Synthesized all-ED Sn,tot(r) with spurious NNMs and large regions with negative values (red isolines). (b) All-ED from val-ED synthesis Sn,val(r) [equation (19)] with spurious NNMs, the most prominent ones shown by red arrows; black isoline steps of 0.0078 e− bohr−3. |
