Small-angle scattering

From Wikipedia, the free encyclopedia

Small-angle scattering (SAS) is a scattering technique based on the deflection of a beam of particles, or an electromagnetic or acoustic wave, away from the straight trajectory after it interacts with structures that are much larger than the wavelength of the radiation. The deflection is small (0.1-10° for SANS) hence the name small-angle. SAS techniques can give information about the size, shape and orientation of structures in a sample.
