Stern-gerlach vs zeeman effect = paradox?

  1. Jun 25, 2014 #1
    This may be a stupid question, but I am reviewing for the physics gre and can't help but see the zeeman effect and stern-gerlach experiments as contradictions. In the Zeeman effect, a neutral atom energy level will split into 3 levels (or 2 or more if take into account anomalous zeeman), but in stern-gerlach, it always only splits in two (the beam deflected upwards has higher energy than the beam deflected downwards).

    Could someone please help me resolve this contradiction?
