Difference-Fourier maps (top) and Fourier maps (bottom) for Ce1, Au, As1 (all x1–x4) and As3 (x2–x4), bold lines: calculated atomic modulation functions for Ce1 (blue), Au (black), As1 (green) and As3 (red); steps of electron densities 0.5 e Å−3 per line in the difference-Fourier maps and 40 e Å−3 per line for Ce, Au, 20 e Å−3 per line for As in the Fourier maps. Ce2 and As2 are not shown since they exhibit a similar behavior to Ce1 and As1 (cf. Fig. 8). |
