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 .

No, because photons are unaffected by gradient of magnetic field. I believe we discussed this three weeks ago. See:If we did this experiment with photons , the photon can have a spin of 1, 0 , -1 ,

They have magnetic dipole moment. Reason this is so is neutron is composite particle made of three charged quarks.ok i see , thanks for the answer. Then why are neutrons affected by the magnetic field
And, just to be clear - photons always have spin 1. They can have different projections of spin 1 and -1. If it was ordinary particle, it would also have 0 projection, but it doesn't. Long story short: lack of rest mass removes that state. If photons had 0 projection state, that would be seen as longitudinal polarized light.... the photon can have a spin of 1, 0 , -1 , right , so then we would expect to see 3 paths correct .
If you replace the Stern-Gerlach apparatus with a calcite crystal then you can do the analogous experiment with photons.If we did this experiment with photons , the photon can have a spin of 1, 0 , -1 ,

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'.If you replace the Stern-Gerlach apparatus with a calcite crystal then you can do the analogous experiment with photons.
I thought that the original post had to do with doing theFair 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'.
Hence the "fair enough" that preceeded everything I said. I take your point.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!

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 .They have magnetic dipole moment. Reason this is so is neutron is composite particle made of three charged quarks.
WRONG>They would behave as a silver atom would, determined by their dipole moment, not their spin.<WRONGok 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 expirment with neutrinos what would we excpect to see , Neutrino's are neutral in charge but have a spin of 1/2
EDIT: Sorry, tired... I forget we're talking about a neutrino, not a neutron; In my post #11 I was thinking "neutron".so a neutrino with no charge has a dipole moment , what gives it a dipole moment
But the neutrino has no subparticlesSee 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.
Yeah, I'm in EST (Eastern Standard time aka GMT -5:00) so... yeah, I was just being stupid and sleepy. Sorry crager.But the neutrino has no subparticles
Yeah, pity I couldn't have just made it an "answer" (singular) and not contradictory ones relating to completely different particles!i see , thanks for your answers .
