Definition: effect which occurs when an incident high-energy photon is deflected from its original path by an interaction with an electron

Note 1 to entry: The electron is ejected from its orbital position and the x-ray photon loses energy because of the interaction but continues to travel through the material along an altered path. Energy and momentum are conserved in this process. The energy shift depends on the angle of scattering and not on the nature of the scattering medium. Since the scattered photon has less energy, it has a longer wavelength than the incident photon.

Note 2 to entry: This entry was numbered 393-13-22 in IEC 60050-393:2003.
