Hey,
I'm having trouble interpreting a question, as the solutions say something different... Anyways the question part d) below:
So we want to determine the expectation value of the y-component of the electron spin on the eigenstate of Sx, now I would of thought this was given by:
[tex]<\uparrow_{x}|\hat{S}_{y}|\uparrow_{x}>[/tex]
However in my solutions it uses the Spin operator in the z-direction instead, I'm note exactly sure what it means by the y-component of the electron spin though I'd of thought this y-component would of been represented by the Spin operator referring to the y components i.e. Sy.
Can someone confirm this? OR tell me why I'm wrong!
Thanks,
SK
