nuclear-scattering amplitude
1Scattering 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… …
2Scattering 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… …

4Delbruck 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 …

6History of string theory — 1943 1958: S Matrix String theory is an outgrowth of a research program begun by Werner Heisenberg in 1943, picked up and advocated by many prominent theorists starting in the late 1950s and throughout the 1960s, which was discarded and… …
7Virtual particle — In physics, a virtual particle is a particle that exists for a limited time and space, introducing uncertainty in their energy and momentum due to the Heisenberg Uncertainty Principle. (Indeed, because energy and momentum in quantum mechanics are …

9Superstring theory — is an attempt to explain all of the particles and fundamental forces of nature in one theory by modelling them as vibrations of tiny supersymmetric strings. It is considered one of the most promising candidate theories of quantum gravity.… …
10Extended X-Ray Absorption Fine Structure — (EXAFS), or more simply X ray Absorption Spectroscopy (XAS), is an experimental method in physics and chemistry of determining the bonding of solids by analyzing oscillations in x ray absorption versus photon energy that are caused by… …
