摘要：

Neutron diffraction studies of the diffuse features around main and satellite reflections of high quality single crystals of Bi2Sr2CaCu2O8+x (Bi-2212), show that extra 'forbidden' reflections and other anomalous diffuse features are a function of crystal quality and not part of the inherent crystallographic structure.
