WebThe diffraction on crystals, especially in the past, and currently on multilayer mirrors, are used below 1 keV. At higher energies, up to some tens of keV, the photoelectric effect is exploited nowadays, while Thomson scattering was previously used. The Compton scattering instead is exploited in the 100 keV energy range. Compton scattering is an example of inelastic scattering. The incident photon loses energy in the lab frame, which centuries of practice had identified with inelastic scattering—even though, in the c.m. frame, the respective masses remaining the same, no new species are created and kinetic energy is conserved, the mark of an elastic collision. As a result, HEP and nuclear physic…

WebThe four types of interactions are: photoelectric (PE), Compton scattering (C), pair production (PP), and Thomson or Rayleigh scattering (R). Since most industrial radiography is done in the 0.1 to 1.5 MeV range, it can be seen from the plot that photoelectric and Compton scattering account for the majority of attenuation encountered. http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/comptint.html WebThe only differnce between photoelectric effect and compton effect is that in Photoelectric effect,gamma rays (photons) give ful of its energy to eject electron and itself disappear while in compton effect gamma rays give some of its energy to electron and the the rest of energy carry itself and not disppear. software intangible or fixed asset
