Energy splitting of the magnetic sub levels

  1. Mar 18, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate the energy splitting of the magnetic sub levels of a 3S1 term in a magnetic field of 1.5 T.

    3. The attempt at a solution
    From the term symbol 3S1 I can conclude:
    S -> L=0
    subscript 1 -> J=1
    superscript 3 -> 3=2S+1 -> S=1

    Therefore I have two electrons with spin +1/2 so the corresponding electron configuration is
    1s12s1

    I know that Electron in an magnetic filed has potential energy:
    E=μ*B , where μ=-gsμb*S/hbar

    But I don't know how to calculate the splitting in energy from this.
