Homework Help: Spin orbit coupling

  1. Feb 26, 2010 #1
    1. The problem statement, all variables and given/known data
    The 4p → 4s transition in 19K produces a pair of lines at 766.49nm and 769.90nm.
    Estimate the value of <(1/r)dV/dr> for the optically active electron in 19 K

    2. Relevant equations

    3. The attempt at a solution
    help needed urgently please. All i know so far is E=hc/(lamda) so therfore
    dE=hc/(lamda)^2 d(lamda)

    How does the spin-orbit interaction affect the energies of the 4s and 4p states? How is <(1/r)dV/dr> related to the spin-orbit interaction? Start there.
