• Small-angle X-ray scattering — (SAXS) is a small angle scattering (SAS) technique where the elastic scattering of X rays (wavelength 0.1 ... 0.2 nm) by a sample which has inhomogeneities in the nm range, is recorded at very low angles (typically 0.1 10°). This angular range… …   Wikipedia

• Small-angle neutron scattering — (SANS) is a laboratory technique, similar to the often complementary techniques of small angle X ray scattering (SAXS) and light scattering. These are particularly useful because of the dramatic increase in forward scattering that occurs at phase …   Wikipedia

• Small-angle approximation — is a useful simplification of the laws of trigonometry which is only approximately true for finite angles, but correct in the limit as the angle approaches zero. It involves linearization of the trigonometric functions (truncation of their Taylor …   Wikipedia

• 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 …   Wikipedia

• Small-angle X-ray scattering — SAXS ou Small Angle X Ray Scattering est une technique permettant de caractériser la morphologie de matériaux à des échelles allant grosso modo de 1 nm à 100 nm.
