WebElectron scattering (Thomson scattering) A single, isolated electron cannot absorb a passing photon (why not?), but it can scatter it into some other direction. This is a simple process, depending only on the "Thomson cross section" of the electron. People sometimes use this scattering cross section to define the "radius" of an electron.
