Ok! Thank you so much!

Thank you, cosmic dust! I have one question (doubt), if U|j,m\rangle is an eigen-state of J_z, therefore U|j,m\rangle=|j,-m\rangle, because J_z(U|j,m\rangle)=J_z|j,-m\rangle=-m|j,-m\rangle. Isn't it?

Homework Statement How to prove that for any representation of the spin, the state e^{-i{\pi}J_x/\hbar}|j,m\rangle is proportional to |j,-m\rangle The exponential term is the rotation operator where J_x is the x-component of the total angular momentum operator, and |j,m\rangle is an...
