Homework Help: X-component of angular momentum, Lx, acting on |n,l,m>

  1. Feb 23, 2010 #1
    1. The problem statement, all variables and given/known data

    I need to know what the eigen value of Lx would be if, Lx|n,l,m>.

    2. Relevant equations


    3. The attempt at a solution

    I have a mixed state I need to apply Lx tp, but I'm not sure how! If anyone known how to put this in terms of L, Lz, or L+-, I would really appreciate the help!

    Express Lx in terms of L+ and L -, then operate on |n,l,m> and see what you get.
