Small angle scattering of x-rays

WebbSmall-angle X-ray Scattering (SAXS), also known as simply Small Angle Scattering (SAS) refers by definition to experiments where the scattering angle 2θ is small, generally less than 10°. Following Bragg's Law, this implies that the length scale of the objects being probed is fairly large, typically in the range between 3 and 100 nm.
