The document details the Compton effect, discovered by Arthur Holly Compton in 1923, which describes the scattering of high-energy photons that release electrons from atoms, supporting Einstein's photon theory. It highlights the effect's significance in radiobiology, material physics, and gamma spectroscopy, emphasizing its applications in radiation therapy and the detection of gamma rays. Additionally, the document includes the experiment's observations of intensity versus wavelength at various scattering angles.

3. FIRST INTRODUCED
The Compton effect was first demonstrated in 1923
by Arthur Holly Compton (for which he received a
1927 Nobel Prize in Physics)
Compton's graduate student, Y.H. Woo, later
the effect.

4. DEFINITION
• The Compton effect (also called Compton scattering) is the result
of a high-energy photon colliding with a target, which releases
loosely bound electrons from the outer shell of the atom or
molecule .
• The scattered radiation experiences a wavelength shift that cannot
be explained in terms of classical wave theory, thus lending support
to Einstein's photon theory.
• Probably the most important implication of the effect is that it
showed light could not be fully explained according to wave
phenomena.

5. APPLICATIONS
• Compton scattering is of prime importance to radiobiology, as it happens
to be the most probable interaction of high energy X rays with atomic
nuclei in living beings and is applied in radiation therapy.
• In material physics, Compton scattering can be used to probe the wave
function of the electrons in matter in the momentum representation.
• Compton scattering is an important effect in gamma spectroscopy which
gives rise to the Compton edge, as it is possible for the gamma rays to
scatter out of the detectors used. Compton suppression is used to detect
stray scatter gamma rays to counteract this effect.

observed by Compton for
the three scattering angles
show two peaks , one at
the wavelength λ of the
incident X-rays and the
other at a longer
