ABSTRACT
Z (neutral current) Neutral intermediate boson discovered in proton-antiproton collisions.
Zeeman effect The splitting of spectral lines of atomic or molecular radiation due to the presence of a static magnetic field. One distinguishes between the normal Zeeman effect for systems with zero spin and the anomalous Zeeman effect, which involves both an orbital and a spin magnetic moment. The latter effect changes into the Paschen-Back effect in very strong magnetic fields.
