Spin orbit interaction

  1. Mar 26, 2007 #1
    1. The problem statement, all variables and given/known data
    The general expression for potential energy of a magnetic dipole placed in magnetic field B is given by,
    E = -m.B
    Where m=magnetic dipole moment
    It is given in a book that due to spin orbit interaction, the potential energy possessed by an electron can be written as,
    E(s) = K(L.S)

    They argue that m is proportional to S(spin quantum number) and B is proportional to L(orbital quantum number).Hence the expression.What is K in the above expression? They have calculated the value of K in one of the problems and I found that it has different values for different atoms.

    2. Relevant equations

    3. The attempt at a solution
