www.nrc.govFeb 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.

experimentationlab.berkeley.eduThe 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 ...
Derivation of Compton’s Equation - Physics Courses
courses.physics.ucsd.eduCompton’s Equation Let 1 and 2 be the wavelengths of the incident and scattered x rays, respectively, as shown in Figure 3-18. The corresponding momenta are p 1 = E 1 c = hf 1 = h 1 and p 2 = E 2 c = hf 2 = h 2 using f c. Since Compton used the K line of molybdenum ( 0.0711 nm; see Figure 3-15b), the energy of the incident x ray (17.4 keV) is ...

Interactions of Photons with Matter - MIT OpenCourseWare
ocw.mit.eduIn Compton scattering, the incoming gamma-ray photon is deflected through an angle θ with respect to its original direction. The photon transfers a portion of its energy to the electron (assumed to be initially at rest), which is then known as a recoil electron, or a Compton electron. • All angles of scattering are possible.

COMPTON EFFECT - Magadh University
magadhuniversity.ac.inThis 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.
