Main Question or Discussion Point

Hi.

I've been reading about Compton scattering and I don't understand what determines the angle at which the electron and photon are scattered. Is it a quantum process, and therefore the value of the angle is "random"? If it is a quantum process, is there any theory that gives the probability distribution for this angle?

Thank you for your time.

Yes and yes.

More precisely, the relevant theory is quantum electrodynamics (QED).

The angular probability distribution for Compton scattering is basically given by the Klein-Nishina formula.
