scattering

 [skat´er-ing]
a change in the direction of motion of a photon or subatomic particle as the result of a collision or interaction.

scattering

Etymology: ME, scateren
a change in the direction of photons caused by the interaction between photons and matter. In coherent scattering, an incident photon interacts with matter and excites an atom, causing it to vibrate. The vibration causes the photon to scatter. Also called Thompson scattering, unmodified scattering. In Compton scattering an incident photon interacts with an orbital electron, transferring some of its energy to that electron. The electron is ejected, and the photon is scattered.
