摘要：

The diffuse scattering in WO3 has been investigated using high-resolution X-ray methods. The structure of the (040)/(400) diffraction profiles in a densely twinned orthorhombic crystal has been mapped. The scattering is characterised by strong, well defined Bragg peaks with a diffuse streak between these of intensity three orders of magnitude lower, arising from the domain walls. Comparison with a simple analytical model for the scattering from such a microstructure suggests an effective domain wall width of around 4 unit cells.
