Figure 3
Scattered intensities as a function of the diffraction angle 2θ for (a) Na1.58CuO2 and (b) Na1.62CuO2. The observed patterns (diamonds), the best Rietveld-fit profiles (line), reflection markers and the difference curves between observed and calculated profiles are shown. Wavelengths are λ = 0.65046 Å for Na1.58CuO2 and 1.54059 Å for Na1.62CuO2. Black reflection markers indicate the main reflections; green (online) or grey (in print) reflection markers indicate satellite reflections. |
