Spin-orbit coupling

  1. Jan 6, 2006 #1
    why does spin-orbit coupling have a positive and negative sign?

    What exactly are you referring to?
  4. Jan 7, 2006 #3
    the spin orbit coupling in atoms that have more than one electron in modern physics...

    That part was obvious but were you referring to a specific formula like the SO-hamiltonian or something?

    no.... sorry!!! my mistake!!! it's why does the z component of the spin angular momentum have a positive and negative sign?

    You mean the eigenvalues, right...? Well, basically, group theory explains why...
