Compton scattering

The diagram to the right shows two Compton scatterings happening sequentially.

Afterwards it flies on as if nothing has happened, even though a little bit of Compton scattering has taken place.

Compton scattering is the predominant interaction between X-rays and soft tissue in medical imaging.

The amount of energy loss by Compton scattering is related to the number electrons per unit volume of formation.

Inverse Compton scattering is important in astrophysics.

Compton scattering is an elastic scattering of a photon by a free charged particle, usually an electron.

The number of high-energy gamma rays is controlled by compton scattering, hence by formation density.

"Stimulated Compton scattering of hydromagnetic waves in the interstellar medium", Astrophys.

Compton scattering is an inelastic scattering of the X-ray photon by an outer shell electron.

In material physics, Compton scattering can be used to probe the wave function of the electrons in matter in the momentum representation.

Compton scattering (incoherent scattering)

Compton scattering is an example of inelastic scattering, because the wavelength of the scattered light is different from the incident radiation.

Compton scattering is thought to be the principal absorption mechanism for gamma rays in the intermediate energy range 100 keV to 10 MeV.

Both devices exploit the spin-dependent cross section for Compton scattering of circularly polarised photons off positrons to measure the beam polarisation.

In 1959, Riazuddin was the first one to use the dispersion relation for Compton scattering of virtual photons on pions to analyse their charge radius.

If the photon has a lot of energy, compton scattering( thousands of eV) or pair production( millions of eV) may take place.

Magnetic Compton scattering is an extension of the previously mentioned technique which involves the magnetisation of a crystal sample hit with high energy, circularly polarised photons.

Although nuclear Compton scattering exists, Compton scattering usually refers to the interaction involving only the electrons of an atom.

Radio-loud quasars can also produce X-rays and gamma rays by inverse Compton scattering of lower-energy photons by the radio-emitting electrons in the jet.

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 scattering is of prime importance to radiobiology, as it is the most probable interaction of gamma rays and high energy X-rays with atoms in living beings and is applied in radiation therapy.

Although these semiclassical models contributed to the development of quantum mechanics, many further experiments starting with Compton scattering of single photons by electrons, first observed in 1923, validated Einstein's hypothesis that light itself is quantized.

The density log measures the bulk density of a formation by bombarding it with a radioactive source and measuring the resulting gamma ray count after the effects of Compton Scattering and Photoelectric absorption.

Compton scattering is relatively independent of the atomic number of the absorbing material, which is why very dense materials like lead are only modestly better shields, on a per weight basis, than are less dense materials.

And he proposed a theory that they were produced in interstellar space as by-products of the fusion of hydrogen atoms into the heavier elements, and that secondary electrons were produced in the atmosphere by Compton scattering of gamma rays.
