Coherent crystal diffraction

Low-angle diffraction patterns recorded on the rear pnCCDs, revealing coherent diffraction from the structure of the photosystem I nanocrystals, shown using a logarithmic, false-colour scale. The Miller indices of the peaks in a were identified from the corresponding high-angle pattern. In c we count seven fringes in the b* direction, corresponding to nine unit cells, or 250 nm. Insets, real-space images of the nanocrystal, determined by phase retrieval (using the Shrinkwrap algorithm15) of the circled coherent Bragg shape transform.
