Compton scattering factors for spherically symmetric free atoms," The Journal of Chemical Physics, vol.
This process, which measures double diffractive deeply virtual
Compton scattering for two spacelike photons, is illustrated in Figure 8.
In 1927, Klein (5) discussed how the interaction between an electron and an electromagnetic field including
Compton scattering should be treated quantum mechanically.
This is because the process of
Compton scattering is a predominant mechanism [20].
Compton scattering is an interaction between photons and charged particles such as electrons [4,5].
For
Compton scattering the Z dependence is linear and the dominant energy region varies within the range between 150 keV and 3 MeV.
where [mu] is X-ray linear attenuation coefficient, [rho] is the electron density, a is a fitting parameter, Z is the effective atomic number, E is X-ray photon energy, and [f.sub.KN](E) is the Klein-Nishina function which yields the electronic cross section of
Compton scattering. Finally X-ray photons are transformed into visible light photons detected by back-end optoelectronic devices.
It was observed that the variation is negligible between 0.5 and 5MeV where
Compton scattering dominates.
Individual chapters are devoted to the main branches of inelastic X-ray scattering: nonresonant inelastic X-ray scattering with characteristic valence electron excitations, nonresonant inelastic X-ray scattering with core- electron excitation, X-ray Raman scattering, the
Compton scattering regime, and resonant inelastic X-ray scattering (RIXS) spectroscopy.
These devices use the gamma-electron spin dependent part of the
Compton scattering cross section to filter out gammas of a particular polarization state.
Because of the minimal angle of the beam, background "white" radiation and
Compton scattering are minimized, thereby increasing the sensitivity of the analysis.
Key words: zero degree electron spectroscopy,
