Homework Statement
[itex] |\psi >=a|z>+b|-z> [/itex]
find [itex] <S_x > [/itex]
The Attempt at a Solution
So I just need to find
[itex] <S_x>=({|<x|\psi >|}^2-{|<-x|\psi>|}^2)\frac{\hbar}{2} [/itex]
right
Yes, that will get you the answer. If you know the matrix representations of [itex] S_x [/itex], [itex] |z> [/itex], and [itex] |-z> [/itex], then you can also just calculate directly [itex] <S_x>=<\psi |S_x|\psi > [/itex].Homework Statement
