<-- deals with electron spin and angular momentum all day long...cool but hard.:cool:

<--- Taking a first year spectroscopy course... REALLY cool stuff.

Are you a student or does your job have to do with that?

They don't "spin" in any other direction. As to why they don't, take an advanced quantum mechanics course because I don't understand the reasoning. :eek:

Electrons spin in two directions here: in the direction of the beam and 180 degrees out of phase. So I cannot vote in your poll.

I like spin up. They're a better sort of electron...more honest, harder working...an electron you can depend on.

Oh and due to the dipoles and quads (and even the correctors to a small extent) the electrons' spin "precesses" as the electrons make their way around the machine. 10 times in a 5 pass machine. :)

Electrons can have a spin in any direction. The projection of their spin along any given axis is quantized and can only have the values + or - hbar/2.
