![]() Here I am stuck since this does not give me the required expression for the shift - just transforming frequencies to the corresponding wavelength does not give me the required result. Which after a little bit of algebra becomes $-$ Therefore from equations $(1)$ and $(2)$, we get $-$ Where $T$ is the energy given to the electron by the photon, which is essentially $h (\nu - \nu_0)$. Now we come to energy conservation: The total energy of the electron is given by $$p c \cos \phi = h \nu_0 + P c - h \nu \cos \theta$$ $$p c \sin \phi = h \nu \sin \theta$$ Where $\nu$ is the frequency of the electron after scattering, $p$ is the momentum of the electron after scattering, and $\phi$ is the electron scattering angle. Then momentum conservation gives, for the $x$- and $y$- axes respectively $-$ ![]() Suppose the photon and the electron are both moving initially along the $x$-axis. In proving this, I started in the same way as in the derivation for "stationary electron" - conservation of momentum and energy along each axis. $$\Delta \lambda = 2 \lambda_0 \frac$ is the initial energy of the electron. The book tells us that this shift is given by Compton earned the Nobel Prize in Physics in 1927 for this new understanding about the particle-nature of photons.In a problem from Bransden and Joachain's Quantum Mechanics, it is asked to calculate the Compton wavelength shift, but the electron is now moving, with a momentum $P$, in the same direction as the approaching photon. H.Compton in 1923 at Washington University in St. The Compton scattering was observed by A. The energy transferred to the recoil electron can vary from zero to a large fraction of the incident gamma ray energy, because all angles of scattering are possible. The photon transfers a portion of its energy to the recoil electron. This deflection results in a decrease in energy (decrease in photon’s frequency) of the photon and is called the Compton effect. When the incoming photon is deflected only slightly, little energy is transferred to the electron. View solution > In a Compton effect experiment, the wavelength of. the recoil electron and the incident photon are coplanar Reason (R) : In Compton scattering energy is conserved. The fraction of the photon energy that is transferred depends on the scattering angle. Click hereto get an answer to your question The wavelength of scattered radiation when it undergoes compton scattering at an angle of 60o. In Compton scattering, the incident gamma ray photon is deflected through an angle Θ with respect to its original direction. Other articles where recoil electron is discussed: radiation measurement: Compton scattering: it scattered, producing an energetic recoil electron. This deflection results in a decrease in energy (decrease in photon’s frequency) of the photon and is called the Compton effect.Ĭompton scattering is the inelastic or nonclassical scattering of a photon (which may be an X-ray or gamma ray photon) by a charged particle, usually an electron. Definition of Compton Scattering In Compton scattering, the incident gamma-ray photon is deflected through an angle Θ with respect to its original direction.
