Homework Help: Magnetic alignment in a strong B-field

  1. Apr 2, 2007 #1
    1. The problem statement, all variables and given/known data

    The question is on the behavior of the magnetic and spin axes in a strong B-field (the Paschen-Back Effect, I believe it's called. Anyway...). I've got almost everything nailed down, except for one thing. In the example I've looked up http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/paschen.html#c1", there doesn't seem to be a state for ml=1, ms=-1/2 and similarly, ml=-1 and ms=1/2.

    Why can't the orbital and spin angular momenta have opposite orientations when they're decoupled by the strong field?
