In gamma-ray spectrometry, the Compton edge is a feature of the measured gamma-ray energy spectrum that results from Compton scattering in the detector material. It corresponds to the highest energy that can be transferred to a weakly bound electron of a detector's atom by an incident photon in a single scattering process, and manifests itself ...

Compton Continuum. In the crystal, a gamma-ray undergoes many interactions, but for intermediate energies, Compton scattering dominates. In Compton scattering, the incident gamma-ray photon is deflected through an angle Θ for its original direction. The photon transfers a portion of its energy to the recoil electron. The energy transferred to ...

Compton scattering is another way gamma rays can interact in the crystal. Exercise 1 Compton scattering is a purely kinematic scattering of an incident gamma photon of energy E with an electron (mass m) in the crystal that is either free or loosely bound (p e ˇ0). Use conservation of energy and momentum to show that when the gamma

The recoiling electron’s energy is deposited in the crystal while the scattered photon exits the crystal undetected. The recoil energy varies from a ...

2015年4月27日 · I found an article/demonstration by David Prutchi also very useful for understanding Compton interactions. He goes into more detail about the lower end of the Compton plateau. The Compton Peak (or "Compton minimum" ) is caused by 180 degree back-scattered photons in or near the source.

“Compton Plateau,” which is produced by Compton scattering of gamma rays within the NaI(Tl) scintillation crystal. Note that when the scattered gamma photon escapes from the crystal,

The Compton effect is the elastic scattering of photons from electrons. As a reaction, the process is: γ +e −→ γ +e . Since this is a two body elastic scattering process, the angle of the scat-tered photon is completely correlated with the energy of the scattered photon by energy and momentum conservation. This relation is usually ...

The Compton Plateau Make several measurements of both spectra with the source in a shelf below the Nal detector. Choose times sufficiently long so that statistics are not a problem. Do you need to perform background subtraction? Transfer the file to Kaleidagraph and plot a spectrum for each of the two sources On this
