Compton effect or Compton scatter is the most importantmain cause of scattered radiation in a material. It occurs due to the interaction of the X-ray or gamma photon with the outermost shell (valence shell(and hence loosely bound) electron valence electron at the atomic level. The resultant incident photon gets scattered (changes direction) as well as ejects the electron (recoil electron), which further ionizes other atoms. Therefore the Compton effect is a partial absorption process and as the original photon has lost energy, this is known as Compton shift (the shift being a shift of wavelength/frequency).
Probability of comptonCompton effect
- directly proportional to
- number of outer shell electrons, i.e., the electron density.
- physical density of material
- inversely proportional to
- photon energy
- does not depend on
- atomic number (unlike photoelectric effect and pair production)
