Schematic of [111,\bar111/200] three-beam multiple diffraction in reciprocal space of Ge, where only the 111 reflection is represented, considering the [\bar111] beam travels in a symmetrical direction with the plane of symmetry (100) at incident X-ray energies of E = E1 in (a) and E = E2 (>E1) in (b) with rectangles OPQR and PP′O′O representing projections on the [\left({01\bar1}\right)] and (100) planes, respectively. [\left({01\bar1}\right)]: entrance surface; Ko: incident X-ray wavevector; K111: 111-reflected X-ray wavevector; g111: diffraction vector of the 111 reflection.
