Figure 1
CXD measurements of the paired diffraction peaks arising from the standing-wave illumination at grazing incidence. Each series represents numbered frames taken from a rocking scan, passing through the centre of the Bragg peak. The values of the rocking angle, θ, are indicated below each panel. The label refers to the data set as referenced in the text. The top two rows are on the same crystal with different incidence angles αi, while the bottom row is a different crystal. |
