Homework Help: Atomic Physics - L-S and J-J coupling

  1. Nov 17, 2012 #1
    1. The problem statement, all variables and given/known data
    2 valence electron atom.
    n, l, s are : 5, 0, 1/2
    n, l, s are : 4, 1, 1/2

    Assume LS coupling and find the possible values of L and then J.



    2. Relevant equations
    None


    3. The attempt at a solution
    I am not really sure. All I know is there's something like, take quantum number N, L and S and then something goes from L+S to L-S

    Also, in addition to this question, if someone can link me with some text where I can read and understand about LS and JJ coupling so that I can do such type of problems, it would be great.

    Thanks
