Thomson scattering — In physics, Thomson scattering is the scattering of electromagnetic radiation by acharged particle. The electric and magnetic components of theincident wave accelerate the particle. As it accelerates, it in turn emits radiation and thus, the wave … Wikipedia
Rutherford scattering — In physics, Rutherford scattering is a phenomenon that was explained by Ernest Rutherford in 1911,[1] and led to the development of the Rutherford model (planetary model) of the atom, and eventually to the Bohr model. It is now exploited by the… … Wikipedia
X-ray Raman scattering — (XRS) is non resonant inelastic scattering of x rays from core electrons. It is analogous to Raman scattering, which is a largely used tool in optical spectroscopy, with the difference being that the wavelengths of theexciting photons fall in the … Wikipedia
Eddington luminosity — The Eddington luminosity (also referred to as the Eddington limit) in a star is defined as the point where the gravitational force inwards equals the continuum radiation force outwards, assuming hydrostatic equilibrium and spherical symmetry.… … Wikipedia
radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… … Universalium

Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
Reionization — in the universe. The universe is currently ionized, in this sense.The first phase change was , which occurred at a redshift z = 1100 (400,000 years after the Big Bang), due to the cooling of the universe to the point where the rate of combination … Wikipedia
Emission coefficient — is a coefficient in the power output per unit time of an electromagnetic source, a calculated value in physics. It is also used as a measure of environmental emissions (by mass) per MWh of electricity generated, see: Emission factor. Scattering… … Wikipedia
