So if you measures the spin of an electron in a Hydrogen atom (which I understand requires a magnetic field to eliminate the degeneracy of energy levels) in an arbitrary direction(adsbygoogle = window.adsbygoogle || []).push({});

[tex] x^i[/tex]

you would measure plus or minus

[tex]\frac{eh}{2Mc}B_i[/tex]

in Joules. Where [tex]B_i[/tex] is the magnetic field component in the direction [tex] x^i[/tex]

I understand you never measure anything between this.

What about the magnetic field components of the other 2 orthogonal dimensions? Is the spin in those directions also

[tex]\frac{eh}{2Mc}B_i[/tex]

That would give a total intrinsic angular momentum of 3/2.
