Diffraction patterns from a dried chicken tendon. Left is a SAXS pattern recorded with an X-ray image intensifier (exposure time 60 ms). Orders of the 630 Å axial periodicity of collagen are seen. Right is a WAXS pattern recorded with C9728DK (exposure 0.4 s). The strong arc is the meridional peak at a Bragg spacing of 2.9 Å. The fibre axis of the specimen was vertical. The X-ray energy was 15.0 keV. |
