Zusammenfassung:
Measurements of the neutron-energy-loss spectrum of CeAl2, made using a triple-axis spectrometer, reveal the existence of two inelastic lines in the paramagnetic regime. Only a single line (Γ7→Γ8) is expected from the cubic symmetry of the crystal field. The origin of the two lines is attributed to the removal of the degeneracy of the excited Γ8 electronic state by the action of the dynamic Jahn-Teller effect.
