Recently, I read the Stern-Gerlach experiment
and I have a question about the source

use free electrons beam instead of Ag atoms beam
is the screen still two lines (electron spin up & down)?

But the truth is that there is a region(pattern) not two obvious lines on the screen
because the electrons can't be polarized in the S-G equipment
I'm just curious that
how to calculate it to prove there isn't two lines on the screen?

Can any gurus derive it and show me?
Thank you! smile.gif

there is a information which i found
jstor search "27757542"
(A History of the Question: Can Free Electrons be Polarized?)
but the context doesn't have the derivation@@ (just interpret the history...)

Hard question for me.
PhysOrg scientific forums are totally dedicated to science, physics, and technology. Besides topical forums such as nanotechnology, quantum physics, silicon and III-V technology, applied physics, materials, space and others, you can also join our news and publications discussions. We also provide an off-topic forum category. If you need specific help on a scientific problem or have a question related to physics or technology, visit the PhysOrg Forums. Here you’ll find experts from various fields online every day.
