Wide Angle X-ray Scattering (WAXS) and Small Angle X-ray Scattering (SAXS) obey the same Bragg's Law (2dsinθ=nλ), but with different distance from sample to detector. With a distance about 384 mm in this work, the WAXS can measure the structure from 0.12 nm to 0.45 nm, which correspond to the crystal lattice, while SAXS can measure the structure from 10 nm to 80 nm, with a distance of 2484 mm. In a SAXS curve, the strength reflect the number of defects, while the q range reflect the size of the defects.
How do the WAXS and SAXS differ? How do these experiments differentiate between increasing the number of defects and the size of the defects?
