Figure 2
Dynamical and kinematical intensities of a diffracted wave at the crystal surface in symmetric Bragg reflections (a), (b) 440 and (c) 220 from a 20 µm-thick diamond crystal bent to a radius of 10 cm. The X-ray energy is 12 keV. Dynamical diffraction calculations for the X-ray susceptibilities of the respective reflections (black lines) are repeated taking susceptibility smaller by a factor of 2, with the intensity multiplied by a factor of 4 (blue lines). Dynamical diffraction calculations are also performed with the susceptibilities multiplied by factors 2 and 4, and with the respective intensities divided by factors 4 and 16 (grey and red lines). The kinematical intensities calculated by equation (7) are shown by green lines. |
