If we did this experiment with photons , the photon can have a spin of 1, 0 , -1 ,
right , so then we would expect to see 3 paths correct .

cragar said:ok i see , thanks for the answer. Then why are neutrons affected by the magnetic field

eaglelake said:If you replace the Stern-Gerlach apparatus with a calcite crystal then you can do the analogous experiment with photons.
Frame Dragger said:Fair enough, but what would be the point? With AgBr (or some other silver) -> Silver Halide you're exploring the photographic process. With photons you'd be doing some kind of bastardized version of better experimental apparatus'.
eaglelake said:I thought that the original post had to do with doing the
Stern-Gerlach experiment with photons. As pointed out, we cannot do the Stern-Gerlach experiment with photons. I am only pointing out that, just as Stern-Gerlach magnets are used to measure spin, Calcite crystals can be used to measure polarization. As you know, spin 1/2 particles have two eigenvalues, as does polarization. The Stern-Gerlach (Calcite crystal) experiment has two output channels, one for each possible value the spin (polarization). The physics of the two experiments is almost identical. If you understand one, then you understand the other. That's all I was trying to say!

xlines said:They have magnetic dipole moment. Reason this is so is neutron is composite particle made of three charged quarks.
cragar said:ok so if we did this experiment with neutrons , then would we see two different paths for the neutrons , and would the neutrons deflect because of their spin or because of their magnetic moment .
And if we did this experiment with neutrinos what would we excpect to see , Neutrino's are neutral in charge but have a spin of 1/2
cragar said:so a neutrino with no charge has a dipole moment , what gives it a dipole moment
Frame Dragger said:See post #4. If you want to do a bit of research you could take a crack at QCD, a fasciniting subject, but maybe basic E&M first.
cragar said:But the neutrino has no subparticles
cragar said:i see , thanks for your answers .
The Stern-Gerlach experiment with photons is a thought experiment that demonstrates the quantum mechanical principle of spin angular momentum. It involves passing a beam of photons through a magnetic field and observing the deflection of the photons, which indicates their spin orientation.
The Stern-Gerlach experiment is important because it provides evidence for the quantization of spin angular momentum in quantum mechanics. This experiment was one of the first to show that particles have discrete energy states, rather than being continuous.
In the experiment, a beam of photons is passed through a magnetic field that is oriented in a specific direction. The photons have a spin angular momentum, which can either be aligned with or against the direction of the magnetic field. As the photons pass through the field, they are deflected either up or down, depending on their spin orientation. This deflection can be observed and measured.
The Stern-Gerlach experiment with photons was significant because it provided evidence for the quantization of spin angular momentum in quantum mechanics. This concept is now a fundamental principle in our understanding of the behavior of particles at the atomic and subatomic level.
Yes, the Stern-Gerlach experiment with photons has been replicated numerous times, both in its original form and with variations. It has also been performed with other particles, such as electrons and atoms, and has consistently shown the quantization of spin angular momentum in these particles as well.
