There is no any experimental evidence which can show that the free charged particle like free electron absorb photon. In theory like QED, you can assume anything but nature is not bound to follows any weird assumption.

This question is not limited to free electrons, this question has been raised in general. Is there an explanation of the photon absorption mechanism by the atom?

A bunch of atoms does absorb photons. Single atom can absorb a very well defined unique frequency photon.

Dear Gokaran

Thank you for comment, but my question is how a neutral photon is absorbable by a charged particle?

Dear Hossein,

Do you have any experimental evidence that "single" atom will absorb photon?

Dear Gokaraan

Yes, I have.

A photon has shape and 4 meters long, this is not the idea, the experiment shows it.

I reviewed and generalized the Dirac equation and sea, and I found the same properties in the photon structured as I had in reviewing the Pound–Rebka experiment. In addition, I realized that the properties of interactions from the photon structure to the fermions and bosons can be generalized and vice versa.

The result of this review was that photon not only has a structure, but it also is a very weak electromagnetic dipole. But the structure and properties of the electromagnetic dipole of photons were in conflict with modern physics. My hope was that eventually this feature of the photon would be confirmed in the experiment. Finally, in 2016, the following results were obtained in an experiment at the Centre for Quantum Technologies at the National University of Singapore: the photon has two different shapes and is four meters long, and the probability of photon absorption by the atom is about four percent.

These results are entirely consistent with the prediction of CPH theory. Because the photon moves at the speed of light, it is absorbable by an electron which is electrically located in a position to be electrically absorbed.

Recently, in a quantum simulation by physicists at the Federal Institute of Lausanne in Switzerland, it was determined that the photon behaves like a magnetic dipole.

But electricity and magnetism are not separate, that is, a photon is a very weak electromagnetic dipole, which was predicted in CPH Theory. Today, physics and astrophysics are involved with fundamental problems, and physicists believe that this is due to the inability of theories.

The Greatest Unsolved Mystery in Physics

https://www.researchgate.net/publication/330366766_The_Greatest_Unsolved_Mystery_in_Physics

The fact that the photon doesn't carry electric charge doesn't imply that it can't interact with an electron; it just constrains how it can interact.

The constraints are (local) conservation of electric charge and (global) conservation of energy and momentum (among the latter being that the mass of the electron is a Lorentz invariant quantity as is the fact that the photon has zero mass).

So, electron + photon -> electron + photon is a reaction that is consistent with conservation of electric charge and of energy and momentum and, therefore, can occur. An electron absorbs a photon and emits a photon.

electron + photon -> electron is, also, consistent with conservation of electric charge, but isn't consistent with conservation of energy and momentum; that's why it doesn't occur, if the electron isn't bound. An electron can't absorb a photon without something else also occurring. If the electron is bound, it occupies another energy eigenstate. So, if the electron is bound, it can't absorb the energy of any photon-only of that, which can make it occupy some other energy eigenstate.

(The statements about the electron's wavelength and its orbitals don't have anything to do with the original question. Also: one photon = one quantum of electromagnetic energy. The quoted text is really misleading. )

I am not experimentalist, but my vision is unprecedented regarding atom in general. I do not see an atom as a composite of quanta elements, but I see it as intelligent element that is composite of very large number of smart constituent elementary particles. Not to mention the space of atom must be included in any test. Therefore each atom must be treated differently. My theory, if we are smart an atom is smart.

Dear Javad

Thank you for your interesting comment.

In CPH Theory, everything is made up of sub-quantum energies, even photon and electron....

Dear Preston Guynn

I read your interesting article. You have described details of the interaction. But I have shown the reason for the absorption photon by atom. Because of experiment show In 2016, the experiment was conducted and showed a photon has shape and 4 meters long, and the probability of the photon being absorbed by the atom is 4%.

Victor Leong, et, at., Time-resolved scattering of a single photon by a single atom, Nature Communications, 2016, https://www.nature.com/articles/ncomms13716

This experiment is inconsistent with the neutral and point-like photon.

All of my intuition is when we talk about electron, it goes to whole atom itself. Electron by itself does not act until, it gets its order from the center of the atom, i.e. when an gas atom lose its temperature one deg, its loses 1/273 of its volume, or if gain one degree, it gain back 1/273 its volume, therefore an electron goes faster by gaining photon.

Dear Javad Fardaei

Yes, you are right. But consider the main problem is the mechanism of absorption photon by the electron.

The photon is transferred to the electron wich to energy a higher state or is expelled with great energy ..

Dear Luis

This is an old interpretation of the interaction between photons and electrons. That does not explain the details of the action.
