Quantum numbers/ spectroscopic notation

  1. Apr 3, 2012 #1

    This question is from Eisberg's QM textbook,

    I just want to make sure I understand this properly,

    http://img641.imageshack.us/img641/5475/86854232.jpg [Broken]

    Using S' as the total spin, J total angular momentum, and L total orbital momentum,

    For the first case,


    2S'+1 = 2. so S' = 1/2

    L = 0, since S corresponds to L=0

    J = 3/2, but J = S' + L = 1/2 ≠ 3/2

    So this is impossible?




    J = 1,2,3 and in this case J = 3

    So possible?





    J=1,2,3 and in this case J = 3


    These three numbers are the quantum numbers the question wants right? Not little l, s and like the possible magnetic quantum numbers?

    Is this correct? I feel like its not..
