  5. Small-angle scattering - Wikipedia

    en.wikipedia.org/wiki/Small-angle_scattering

    Small-angle scattering (SAS) is a scattering technique based on deflection of collimated radiation 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°) hence the name small-angle. SAS techniques can give information about the size ...
