(a) Part of the azimuth-Bragg 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 [Delta]

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 [Psi]

is the degree of asymmetry. The mean neutron wavelength was about 0.166 nm.
