| Jun 8, 2023 at 11:57 | comment | added | John Doty | @annav Well, it's not quite two different reactions. A photon can scatter from an inner shell electron, with momentum and energy transfers to the atom, but with an outgoing photon of lower energy. Sort of a mixture of Compton and photoelectric. The cross section isn't very high, but calibration spectra for the SDD detectors on NICER exhibit features we interpret as this process. | |
| Jun 8, 2023 at 11:54 | comment | added | medical physics | @annav there are areas where the probability of different matter photon interactions to happen escalates. As you can see in the link. Open the question please. | |
| Jun 8, 2023 at 11:53 | comment | added | medical physics | @annav the link you provided does not weigh in the problem from the perspective I provided in my OP. Here is the link: researchgate.net/figure/… | |

| Jun 8, 2023 at 11:50 | comment | added | anna v | hyperphysics.phy-astr.gsu.edu/hbase/quantum/comptint.html .there is a scattered photon in the Compton scattering, it is two different reactions. Apples with oranges. | |
| Jun 8, 2023 at 11:50 | comment | added | medical physics | @annav open the question thus we can discuss it because clearly there is a misunderstanding or misinformation. My sources clearly states that lower energies than compton increases the chances of photoelectric effect. | |
| Jun 8, 2023 at 11:48 | comment | added | anna v | "The photoelectric effect is typically observed when the energy of the incident light is lower than what is required for both Compton scattering and pair production, but higher than the energy needed for Rayleigh scattering." This is not true, if you read the hyperphysics link the photoelectric effect in physics measurements starts on the surface of metals with quite low energy photons. it is the metals. | |
| Jun 8, 2023 at 11:47 | comment | added | medical physics | @annav please open my question, my question is also about Compton scattering. And the link you provided does not elaborate the problem specific enough as my OP do. | |
| Jun 8, 2023 at 11:43 | comment | added | medical physics | @annav Thank you but I am searching for an explanation for both Compton and the Photoelectric effect in relation to one another comparatively as I mentioned in my OP. | |
| Jun 8, 2023 at 11:43 | comment | added | anna v | As far as physics goes it is a misrepresentation of the photoelectric effect as known in physics , but the link explains why the probability of K shell interaction is high if the energy is available. | |
| Jun 8, 2023 at 11:42 | comment | added | John Doty | This seems to be about x-ray and gamma-ray interactions. | |

| Jun 8, 2023 at 11:32 | comment | added | anna v | This seems a strange quote AFAIK. Can you give a link for these definitions of the photoelectric effect? I know this effect hyperphysics.phy-astr.gsu.edu/hbase/mod2.html | |
