Comp·ton ef·fect

, Compton scattering (kom'tŏn e-fekt', kom'tŏn skat'ĕr-ing)
Change in wavelength of x-rays or gamma rays due to interaction of electron orbiting nucleus and incidental photon, resulting in scattered photons of lower energy and recoil electrons.

Compton scattering

(komp'ton) [Arthur H. Compton, U.S. physicist and Nobel laureate, 1892–1962]
An interaction between x-rays and matter in which the incoming photon ejects a loosely bound outer-shell electron. The resulting change in the direction of the x-ray photon causes scatter, increasing the dose and degrading the radiographic image. Most interactions between x-rays and matter are of this type, esp. at high energies. See: scatter

The corresponding amplitude for deeply virtual Compton scattering is not given by the handbag diagram alone since interactions between the two currents are essential.
Nishina succeeded to derive the famous Klein--Nishina formula, (8,9) calculating the intensity distribution of the scattered wave in the Compton scattering based on the Dirac equation.
In the intermediate photon energy region, the EBF and EABF values are highest because the predominant interaction process is the Compton scattering. In the high-energy region, the photons have been absorbed again because the predominant interaction process is the pair production.

At intermediate energies (0.05 MeV < E < 5 MeV), where Compton scattering is the main photon interaction process, [Z.sub.PIeff] is approximately equal to the arithmetic mean of the atomic number calculated from the chemical formula of the glass samples, <Z> = (1/n)[[summation].sub.i][n.sub.i][z.sub.i].
where [n.sub.0] is the number density of electrons in the core, L is the core length, v is the fraction of electrons that are magnetized, and [[sigma].sub.c] is the Compton scattering cross section due to the circular polarization of the gammas.
Compton scattering is a quantum process that involves the inelastic scattering of a photon by an electron.
Partly because of the versatile monochromators BESSRC-CAT pioneered, BESSRC-CAT users can now avail themselves of numerous experimental techniques, including x-ray absorption fine structure, x-ray scattering (bulk and surface), small-angle x-ray scattering, single-crystal diffraction, powder diffraction, high-energy diffraction, Compton scattering, and magnetic scattering.
Inverse Compton scattering: collisions between photons and energetic nuclei that transfer energy to the former.
Instead, he suggests, a process called inverse Compton scattering may account for the gamma rays.
A high-quality Gamma-beam generated from inverse Compton scattering off relativistic electron beams interacting with an intense laser pulse arouses interest in photonuclear physics and nuclear astrophysics research, characterization of nuclear materials or radioactive waste and so on.
