Figure 11
The deviation δy of the Bragg parameter y from the center of the rocking curve y = 0 (see color scales at the right-hand corner of each figure) in the plane Z = +1 (top), Z = 0 (middle) and Z = −1 (bottom). Each unit change of δy corresponds to half the Darwin width of the Bragg reflection from an unbent perfect crystal. See the text of §4 for definitions of the Z planes. |
