Hi! I have difficulties seeing the cause that make these to concepts diffret. Haken and Wolf writes about the last one: "One speaks of the anomalous Zeeman effect when the angular momentum and magnetic moment of the two terms between which an optical transistion occurs cannot be described by just one of the two quantum numbers s or l., but are determined by both." However in the nomal Zeeman we used the J as a quantum number and therefore used both?! Im not getting this right..
