Figure 7
(a) Comparison between the observed (Yobs, in red) and calculated (Ycalc, in black) neutron diffraction pattern of ThF4. Yobs − Ycalc, in blue, is the difference between the experimental and calculated intensities. The Bragg reflections' angular positions are marked in green. Measurement at λ = 1.667 Å. (b) Sketch of the ThF4 structure showing the ThF8 polyhedra connected by their vertices in green and fluorine atoms in grey. |
