WebSep 25, 2024 · We can represent the magnitude squared of the spin angular momentum vector by the operator (9.1.1) S 2 = S x 2 + S y 2 + S z 2. By analogy with the analysis in Section [s8.2], it is easily demonstrated that (9.1.2) [ S 2, S x] = [ S 2, S y] = [ S 2, S z] = 0. WebThis is formally achieved by projecting the state vector onto the eigenvalues of the operator, as in the discrete case . It happens that the eigenvectors of the position operator form a complete basis for the vector space of states, and therefore obey a closure relation :

WebWhen the probabilities are calculated, the −1 is squared, (−1) 2 = 1, so the predicted physics is the same as in the starting position. Also, in a spin- 1 2 particle there are only two spin states and the amplitudes for both change by the same −1 factor, so the interference effects are identical, unlike the case for higher spins.
