Figure 2
Neutron powder diffraction pattern showing the difference between data measured at T = 1.5 and 30 K, with wavelength λ = 2.567 Å. The solid line shows the result of the Le Bail fit. The blue dashed line shows the difference between observed and calculated intensities. The rows of vertical ticks mark the Bragg peaks for propagation vectors ±[[{1\over 3},{1\over 3},0]] (upper) and [0, 0, 0]. The contribution of [0, 0, 0] is shown by the red curve. The reliability factors (Rodríguez-Carvajal, 1993BB7) are: Rp = 3.14, Rwp = 4.19, Rexp = 1.29 and χ2 = 10.6.
