I never heard that this experiment is carried out with entire atoms; I read a lot about it and saw many videos, and NOT ONCE I heard about entire atoms, just electrons in a magnetic field. I don't want to say I don't believe you. I also didn't try to figure out the technical aspects, how a great...

Yes, rethinking the whole, it doesn't seem correct to me that the electrons that emitted a photon have now different energy than the ones that dindn't. When a stone falls to the ground, its potential energy transforms in kynetic energy and than in deformation/heat? Think if I ask where the...

Yes, this was clear. "Obviously the ones that did emit photons will now have different energy than the ones that didn't." If so, than I have the answer now - didn't think of this possibility. Thank's a lot, seems all clarified now!

You mean in the case where an electron jumps from a higher level energy to a lower one in an atom? In the spin up/spin down experiment there's no such thing as an "electron-nucleus system" (I guess). Or maybe in this experiment the photon is emitted by the electron-field system?

Spin up and spin down are distinct states, yes. But at the beginning we prepared the electrons to be all in the same state (spin up with regard to a magnetic field). If we now say that aligning in a new field part of the electrons emit a photon and part not, it sounds to me as if their...

Ok, thank you, maybe I don't remember correctly. Can anybody tell me if the photon emitted in the spin up/down experiment comes from the electron itself?

I remember being told exactly this in school; why I remember it so clearly is because most students didn't get it right. (I imagine that the potential energy when the object is on top of the mountain makes the difference in mass/weight too?) Anyway, thank you both for your replies. Why I...

Hello all, I'm new here … interesting discussions. My question is: When an electron "jumps" from a higher energy level to a lower one, a photon is emitted. Is it correct to say that it is the electron that emits the photon? Or when an electron aligns in a magnetic field, a photon is either...
