Find all J values of electron configuration

  1. Nov 29, 2011 #1
    1. The problem statement, all variables and given/known data
    Find all permitted J values for electronic configuration 2p3/22

    2. Relevant equations

    Clebsch-Gordan coefficients maybe ?

    3. The attempt at a solution

    Maybe from this ?

    J = L+S,L+S-1,...,|L-S|

    Then I first have to find L and S, and just put them in above equation ?

    Any Hints ?

    No need for C-G coefficients, just read what the spectroscopic symbol means: what do 2, p, 3/2, 2 stand for ?

    Indeed J = L+S,L+S-1,...,|L-S| is useful.

    2 stands for principal quantum number n, p is orbital number l, 3/2 stands for j and the 2 is for two electrons. But I'm not sure about all.

    (I have a lot of work these days, so my responses are delayed)
