What is Compton scattering: Definition and 166 Discussions
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.
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.

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...
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...
What equipment Compton used to measure the wavelenght shift in your experiment ? Some links talk about the use of bragg spectrometer others about the use of ionization chambers.
In this link have some illustrations of spectras resultants of Compton experiments...
Homework Statement
The energy E and momentum P of a relativistic electron and energy ε and momentum p of a photon are related by:
E^2 - P^2c^2 = m_{e}^2c^4 and \epsilon = pc
let E_{i}, P_{i} and E_{f}, P_{f} denote the inital and final energies and momenta of the electron, and let...
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...
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...
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 =...
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...
Any ideas how to do this question ?
In a Compton type experiment X-rays scattered through 90 degrees suffered one percent reduction in energy.What was the incident energy of the X-rays ? You can assume that the electron coiled non-relativistically.
Any help would be really appreciated ...
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...
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...
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...
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...
Hello all,
Can anyone explain to me which electrons contribute in compton scattering?
-Only free electrons;
-Free electrons and weakly bounded to atoms;
-All atomic electrons and free electrons
According to Klein-Nishina formula, photons scatter with all atomic electrons; becouse the...
