Question

from this box through an SGθ device with θ such that cosļ θ-3 and sin| θ = 4, we find that 1%5 are determined to have Se. Assuming that the components of b) are real, argue that there are two distinct q-vectors for l ψ consistent with this result (that is, that differ by more than an overall sign). If we send electrons from this box through an SGx device and find that 77% are determined to have ћ, what is |v) (up to an overall sign)? (Hint: Let the components of] be a and b. Write an expression for the probability in the first case in terms of a and b, use the requirement that l ψ be normalized to eliminate a, and then solve for b. You should find two solutions, one that is quite simple, though the simple solution is not necessarily the correct one.)
