**Self-energy** — In theoretical physics and quantum field theory a particle s self energy Σ represents the contribution to the particle s energy, or effective mass, due to interactions between the particle and the system it is part of. For example, in… … Wikipedia

**Self-adjoint operator** — In mathematics, on a finite dimensional inner product space, a self adjoint operator is one that is its own adjoint, or, equivalently, one whose matrix is Hermitian, where a Hermitian matrix is one which is equal to its own conjugate transpose.… … Wikipedia

**Self-ionization of water** — The self ionization of water (also autoionization of water, and autodissociation of water) is the chemical reaction in which two water molecules react to produce a hydronium (H3O+) and a hydroxide ion (OH−):: 2 H2O (l) ightleftharpoons H3O+ (aq)… … Wikipedia

**Grazing-incidence small-angle X-ray scattering** — (GISAXS) is a scattering technique most commonly done at synchrotron radiation facilities. A related technique also exists for neutron scattering (GISANS). 300px|thumb|right|Scheme 1: GISAXS scattering geometry. The incident beam strikes the… … Wikipedia

**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

**Delbruck scattering** — Delbrück scattering, the deflection of high energy photons in the Coulomb field of nuclei as a consequence of vacuum polarization has been observed. However, the process of scattering of light by light, has not been observed.[1] In both cases, it … Wikipedia

**Carrier scattering** — Defect types include atom vacancies, adatoms, steps, and kinks which occur most frequently at surfaces due to finite material size causing crystal discontinuity. What all types of defects have in common, whether they be surface or bulk, is that… … Wikipedia
