photon scattering
- In radiation measurement: Compton scattering
…it scattered, producing an energetic recoil electron. The fraction of the photon energy that is transferred depends on the scattering angle. When the incoming photon is deflected only slightly, little energy is transferred to the electron. Maximum energy transfer occurs when the incoming photon is backscattered from the electron and…

…momentum to an electron, which recoils. The scattered photon must thus have less energy and momentum than the incoming photon, resulting in scattered X-rays of slightly lower frequency and longer wavelength. Compton’s careful measurements of this small effect, coupled with his successful theoretical treatment (independently derived by the Dutch scientist…
