2ω angle (circle) versus tilting angle of the Bragg (a) and the Laue (b) diffractions. For the Laue tilting angle the position of maximum 2ω angle is −0.05 mrad, consistent with that in Fig. 5; for the 840 Bragg tilting angle the top of the 2ω curve is −15.3 mrad, slightly different from the value of −16.3 mrad in Fig. 5. |
