(a) Part of the azimuthBragg angle relationship for the 222 primary reflection of the diamond structure, (b) and (c) experimental scans for, respectively, symmetric and asymmetric diffraction geometries of Si slabs for different deviations from the mean Bragg angle, and (d) intensity dependence of the MBR effect on the curvature of the crystal. R is the bending radius of the crystal slab and is the degree of asymmetry. The mean neutron wavelength was about 0.166 nm.
