Introduction[ edit ] Fig. Compton scattering occurs in the graphite target on the left. The slit passes X-ray photons scattered at a selected angle. The energy of a scattered photon is measured using Bragg scattering in the crystal on the right in conjunction with ionization chamber; the chamber could measure total energy deposited over time, not the energy of single scattered photons.

However, users may print, download, or email articles for individual use. Index Great experiments of physics Reference: The physicist Arthur Holly Compton used the quantum theory to explain how the scattering of light quantum by electrons takes place, a phenomenon known as Compton effect.
The shift of the wavelength increased with scattering angle according to the Compton formula:. This abstract may be abridged. Click for more detail. The scattered photon has lower energy and therefore a longer wavelength according to the Planck relationship.
Users should refer to the original published version of the material for the full abstract. The shift of the wavelength increased with scattering angle according to the Compton formula: Compton explained and modeled the data by assuming a particle photon esspalhamento for light and applying conservation of energy and conservation of momentum to the collision between the photon and the electron.
An interesting feature of the Compton effect occurs in a frontal collision between the photon and the electron with the photon being backscattered, in which case the energy of the scattered photon is maximum and espalhsmento be even of the order of magnitude of the energy of the incident electron.
Photon beams produced by inverse Compton scattering of laser light by relativistic electrons have scientific, technological, industrial and medical applications. Compton Scattering Arthur H. Related Posts
