jajrussel Posted November 1, 2018 Share Posted November 1, 2018 (edited) I have read that when an electron drops an energy level a photon is given off. Are there any other conditions were a photon is produced? Any other Particle? I'm going to search. I'm just hoping for a shortcut. A point in the right direction.

Annihilation of matter-antimatter. https://en.wikipedia.org/wiki/Annihilation e.g. annihilation of electron-positron: [math]e^- + e^+ \rightarrow \gamma + \gamma + 1.022 MeV[/math] Decay of unstable particles like e.g. neutral pion meson. https://en.wikipedia.org/wiki/Pion [math]\pi^0 \rightarrow \gamma + \gamma + 135 MeV[/math] Link to comment Share on other sites More sharing options...
