Scattering — is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more localized non uniformities in the medium through which they pass. In… … Wikipedia
Scattering cross-section — The scattering cross section, sigma; scat, relates the scattering of light or other radiation to the number of particles present. In terms of area, the total cross section ( sigma;) is the sum of the cross sections due to absorption, scattering… … Wikipedia
Scattering amplitude — The scattering amplitude describes the amplitude of an outgoing, elementary, spherical wave relative to a plane, incoming wave scattered on a point size particle. Since the spherical wave amplitude varies with frac{1}{R} (note, the intensity is… … Wikipedia
scattering function — noun A function which describes the intensity of scattered radiation in any given direction … Wiktionary
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
Helium atom scattering — (HAS) is a surface analysis technique used in materials science. HAS provides information about the surface structure and lattice dynamics of a material by measuring the diffracted atoms from a monochromatic helium beam incident on the sample.… … Wikipedia
Static light scattering — is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein. Measurement of the scattering intensity at many angles allows… … Wikipedia
Dynamic light scattering — Hypothetical Dynamic light scattering of two samples: Larger particles on the top and smaller particle on the bottom Dynamic light scattering (also known as photon correlation spectroscopy or quasi elastic light scattering) is a technique in… … Wikipedia
Rayleigh scattering — This article is about the optical phenomenon. For the magnetic phenomenon, see Rayleigh law. For the stochastic distribution, see Rayleigh distribution. For the wireless multipath propagation model, see Rayleigh fading. Rayleigh scattering causes … Wikipedia
Low-energy ion scattering — LEIS redirects here; for the Hawaiian garland see Lei (Hawaii). Low energy ion scattering spectroscopy (LEIS), sometimes referred to simply as ion scattering spectroscopy (ISS), is a surface sensitive analytical technique used to characterize the … Wikipedia
