(a) Event-based data acquisition allows for filtering detected neutrons, in this case on the goniometer rotation angle around the vertical axis (s1). (b) Elastic scattering in the horizontal plane. Data are symmetrized using reflections about the
[H,K,0] and
[H,0,L] planes. (c) A 0.5°-width region around s1 = 49° is used as background. The efficient subtraction method used is described in the text. (d) Detail cut at
L = 2 shows the removal of the sample environment background (aluminium powder lines). |
