Compton scattering Definition and 167 Threads

Compton scattering, discovered by Arthur Holly Compton, is the scattering of a photon after an interaction with a charged particle, usually an electron. If it results in a decrease in energy (increase in wavelength) of the photon (which may be an X-ray or gamma ray photon), it is called the Compton effect. Part of the energy of the photon is transferred to the recoiling electron. Inverse Compton scattering occurs when a charged particle transfers part of its energy to a photon.

    Compton Wavelength Change: Blue Light & X-Rays

    [b]1. Homework Statement [/b Robinett question One of my homework questions in the Compton scattering section asks: "Evaluate the fractional change in wavelength delta lambda/lamdba, for incident blue light and X-rays? It also gives the wavelength of blue light and X-rays. I do not know what...

    Compton scattering: electron absorbs then emits a photon?

    Hello, In Compton scattering, does the electron absorbs a photon and then emit another photon with another energy?? I couldn't understand how would the electron absorb a FRACTION of the photon's energy which is forbidden in QM. Regards

    Newtonian Solution to Compton Scattering

    Homework Statement I need to derive the Compton scattering formula using Newtonian mechanics, I have it done in relativistic mechanics but can't get the Newtonian version. Homework Equations the solution to the relativistic equation is 1=mc^2(1/E2-1/E1)+cos(theta) for Newtonian...

    Maximum KE, Compton Scattering

    I am asked to find the maximum KE value of the recoiling electron involved in a Compton scattering situation. Obviously, the maximum final Kinetic Energy of the electron would result when as much momentum as possible is imparted on the electron as a result of the collision. If the incident...

    Photoeffect and compton scattering

    I was asked question: "Why in case of photoelectric effect electrons closer to the atom are ejected and in case of Compton effect electrons in the outer shells are emitted from nucleus by x-ray photon?". Well I know that this topic is very deep and one has to carefully select words to explain...

    Compton Scattering of of monochromatic light

    I'm working out a problem from a text concerning the scattering of monochromatic light by free electrons (Compton effect) which asks me to derive expressions for the wavelength shift, electron momentum, and electron scattering angle in terms of the photon scattering angle assuming that the...

    Compton Scattering: Calculating Wavelength from Energy

    If the maxmimum energy imparted to an electron in Compton scattering is 45 keV what is the wavelength of the incident photon? So a compton scattering happens and the energy is 45 keV and I need to find the wavelength of the photon incident to this electron. I think I need to use Lambda =...

    What Is the Minimum Energy of a Photon in a Compton Collision with a Proton?

    For some reason I don't feel like I was given all of the information on this question: A proton at rest is struck by a photon in a Compton collision. If the recoil kinetic energy of the proton is 4.5 MeV, what is the minimum energy of the incident photon (in MeV)? (Take the mass of the proton...

    QM Compton scattering energy loss; check of derivation

    Okay, so the question is an electron of energy 100 MeV collides with a photon of wavelength 3x10^(-3) m (ie: the CMB). What is the maximum energy loss of the electron? After doing a few derivations for formulae, I came up with this one at work...could someone please let me know if there is...

    Quantised Photon Energy and Compton Scattering

    To back me up with some of my chemistry courses this year, I picked up a quantum mechanics book that looked like it included some fairly simple introductions to quantum principles. However, in the first chapter it used Compton scattering, the lowering in wavelength of X rays due to collision...

    Particle Nature of Light versus Compton Scattering Effect

    The Compton scattering effect (1923) seems to be the main evidence that light has a particle-like behavior. What are the other effects that indicate that light has a particle-like behavior? If there are no other effects that indicate that light has a particle-like behavior, and if we find an...

    Questions re Compton scattering

    I am not sure this is the right topic for these questions. They are for the people who are familiar with Compton scattering. Let \Theta be the angle that the trajectory of the scattered photon makes with the trajectory of the incident photon. Suppose \Theta is zero. Does that...
