| coherent radiation | <physics> Any form of radiation in which the phase relationship between sections of the wave at different locations is not random (or incoherent!). Typical example is a laser beam, in which the phase is more or less uniform across the beam and changes along the beam in accordance with the wavelength. Radiation in which the photons tend to correlate with one another, rather than being randomly distributed. (09 Oct 1997) |

| pitch angle scattering | <physics> Scattering (collisional, or due to wave-particle effects) of particles in velocity space, in which the pitch angle (see entry above) is changed. (09 Oct 1997) |
| Compton scattering | <radiobiology> An attenuation process observed for x and gamma radiation in which an incident photon interacts with an orbital electron of an atom to produce a recoil electron and a scattered photon of energy less than the incident photon. (16 Dec 1997) |
| scattering | <radiobiology> The deflection of one particle as a result of collisions with other particles or with waves. See: Elastic. (09 Oct 1997) |
| scattering, radiation | The process in which energy is removed from a beam of light or other electromagnetic radiation and emitted without appreciable change in wavelength. May be considered as the change in direction of a particle or photon owing to a collision with another particle or system. (12 Dec 1998) |
| Thomson scattering | <radiobiology> Scattering of photons by electrons, in the classical (low photon energy) limit. Laser light passed through a plasma will experience Thomson scattering, the spread of the scattered light in energy provides a very good measurement of the electron temperature of the plasma. (09 Oct 1997) |
| light scattering | Particles suspended in a solution will cause scattering of light and the extent of the scattering is related to the size and shape of the particles (in a somewhat complex relationship). (18 Nov 1997) |
