Figure 6
Left: grey-scale plot (black is maximum intensity in the linear plot on the left) of the intensity distributions of the diffracted beam as registered by the photodiode as a function of the angle ϑ (abscissa) and for 29 positions of ψ. The photon energy was 4 keV, and the angle of grazing incidence of θ = 0.64° suppressed the specularly reflected peak (m = 0) the best. Right: the same intensities but on a logarithmic scale, which presents smaller intensities more clearly. In this plot most of the lower index orders are labelled, as are some isolated high-order peaks.
