Homework Help: Quantum Physics/ Need help understanding the spin-allowed (dS=0) dipole transitions

  1. Sep 9, 2011 #1
    1. The problem statement, all variables and given/known data

    Attached PDF. Problem # 2.

    2. Relevant equations
    Used parity selection rule, Assumed Russell-Saunders Coupling


    3. The attempt at a solution
    I only understand the electric dipole allowed transitions from reading. I don't actually understand how they work. For the electron undergoing the transition, dl= +/-1. The d represents delta. For the atom as a whole, the following selection rules apply:
    dS=0, dL=0, +/- 1
    dJ=0, +/-1 except 0<->0
    dMJ= 0, +/-1 except 0<-> for dJ=0
    dML=0, +/- 1
    dMS=0, +/-1
    Laporte selection rule on parity: u <-> g g<-x->g u<-x->u
