Exercise 5.23 Consider a system of total angular momentum j = 1. We want to carry out measurements on 1 0 0 J₂ = h 00 0 00-1 (a) What are the possible values will we obtain when measuring J₂? (b) Calculate (x). (2), and AJ, if the system is in the state j = -h. (c) Repeat (b) for (y). (J), and AJy.
