[QUOTE="rsaad, post: 4386838, member: 442750"] [h2]Homework Statement [/h2] Find the eigenvalues and eigenstates of the spin operator S of an electron in the direction of a unit vector n; assume that n lies in the xz plane. [h2]Homework Equations[/h2] S|m>= h m|m> [h2]The Attempt at a Solution[/h2] This question is from Zettili QM and they have written: n.S|m>= (h/2) m|m> I do not understand why are they taking a half. If I take m=1/2 in [B]S|m>= (h/2) m|m>[/B], I get h/4 but the answer should be h/2, by using [B]S|m>= h m|m>[/B]. So where am i going wrong? [/QUOTE]
