摘要：

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 (78) 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 8 electronic state by the action of the dynamic Jahn-Teller effect. © 1979 The American Physical Society.
