Sa. Stepanov et al., APPLICATION OF THE RENNINGER EFFECT TO X-RAY DOUBLE-PLANE COLLIMATION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 346(1-2), 1994, pp. 385-393
The opportunity of X-ray double-plane collimation due to forbidden Bra
gg reflex simulated by 3-beam diffraction has been studied, both theor
etically and experimentally. It has been shown that the double-plane c
ollimation is provided in both Bragg and Laue cases of forbidden refle
x, but in the latter case the degree of the collimation is much higher
