[edit] Importance of Proof
How important is it to have such a long derivation of the Compton formula? I think it would suffice to drop three-fourths of the steps, and instead highlight the fundamental concept that the equation results from conservation of energy and momentum.

- It's fine to summarize the proof in words, but the derivation itself should remain.
- I say this because many authors of physics and math books are content to skip steps in their publications (and I guess that makes sense since every extra page costs money), but Wikipedia isn't made of paper - it can be as long as we want.
- And one of the reasons Wikipedia is so valuable is because derivations like this are hard to find in the literature, and it's fantastic that we have an opportunity to finally store and share information like this.JabberWok 03:06, 19 December 2006 (UTC)
[edit] recat
I moved the article from Category:Physics to Category:Quantum Mechanics to alleviate overcrowding. StuTheSheep 03:11, Mar 23, 2005 (UTC)
- I moved the article from the heading "Compton efect" under the heading "Compton scattering". The last one is more often used. --Eleassar777 15:13, 30 May 2005 (UTC)
[edit] Derivation image?
The derivation would be greatly helped by an image showing what was going on (for the visual thinkers among us). For examply, it is very hard to see what theta is, exactly. --jonon 09:33, 2 Jun 2005 (UTC)
- I added a diagram and one sentence that clarifies what theta is. --Tim314 22:14, 30 August 2005 (UTC)
[edit] Introduction
It says "which occurs when X-ray (or gamma ray) photons with energies of around 0.5MeV to 3.5MeV interact with electrons". Doesn't it occor when photons with lower energies interact with electrons, too? Isn't it just that the ammount of wavelength change does not depent on the incoming photons' wavelength and that therefore compton scattering can only be observed if the interacting photons have a high energy!? greetings --Space-Marine 01:05, 17 December 2005 (UTC)
[edit] Inconsistency in proof
The lambdas are written with apostrophes in the proof, and with indices in the formula being proved. This might be lead to more confusion than absolutely necessary. — Irrbloss 18:40, 16 May 2006 (UTC)
[edit] Increase in photon energy possible?
Can the photon ever gain energy after the collision? For example, if the electron is moving towards the photon, and the photon is reflected backwards after ejecting the electron, will it have a shorter wavelength and more energy?--SeanMon 23:53, 22 May 2006 (UTC)
- Yes, that's called Inverse Compton scattering. It used to be hiding on its own page (at Inverse Compton scattering), but I've just merged the info about it into this article. --Mike Peel 08:56, 2 August 2006 (UTC)
The formulae are not appearing as they should. This is true for Compton Effect as well.
