Compton effect. The fraction of energy transferred depends on the Compton scattering angle θ and the initial energy of the gamma ray, E0. If the energy of the gamma ray before it is scattered is E0 and the energy of the scattered gamma ray is E, then E0 and E are related by the Compton scattering relationship (2 0 11 1 1cos EE mc −= −θ) (2)

systems, at very low temperature and large fields, the Hall resistance show a step-like (rather than linear) dependence on B. These steps are completely independent of the type of sample and quantitized to values h/e2m, where m is an integer. This is the famous Quantum Hall Effect4. The fundamental quantum of Hall resistance is h/e2 =25,813Ω ...

Feb 04, 2011 · Compton edge Photons Come Directly from Source Compton Scattering – Compton Continuum 19 Compton edge. They are produced when the angle of the scattered gamma ray is 180 degrees. Photons scattered at 180 degrees frequently have energies close to 200 keV. As such, the Compton edge is usually 200 keV to the left of the photopeak.
The Compton scattering process consists of a photon scattering o of a (free) electron. The scattering formula is 0 = h m ec (1 cos ) = c(1 cos ) (1) where 0is the wavelength of the scattered photon, is the wavelength of the incident photon, is the scattering angle, and cis the Compton wavelength of the electron, equals to 2426 fermi (2426 10 15 ...

This eq. 12 was derived By A. H. Compton and it describes the phenomenon known as Compton Effect. The term gives the change in photon wavelength due Scattering with a free electron and it is called Compton Shift. From eq. 12 it is clear that the Compton Shift is independent of the wavelength of the incident photon and depend on scattering angle.
