It has been proved that under certain conditions strong multiple reflections with intensities comparable or even higher than those corresponding to single diffraction process can be excited in the deformed single crystals. This effect is documented on diffraction by cylindrically bent perfect silicon crystals. (C) 2010 Elsevier B.V. All rights reserved.
