“…Because IFMRB are observed for l 14 mm in Fig. 3, a value of " 0 zz in this region is obtained by fitting the IFMRB profile calculated by assuming a value of ð" 0 zz Þ to the measured IFMRB profile for each value of l, as described by and Jongsukswat et al (2012b). The insets of Fig.…”

In X-ray interference fringes accompanied by mirage diffraction, variations have been observed in the spacing and position of the fringes from a plane-parallel Si single crystal fixed at one end as a function of distance from the incident plane of the X-rays to the free crystal end. The variations can be explained by distortion of the sample crystal due to gravity. From the variations and positions of the fringes, the strain gradient of the crystal has been determined. The distribution of the observed strain agrees with that expected from rod theory except for residual strain. When the distortion is large, the observed strain distribution does not agree with that expected from rod theory.
