Abstract
Dipole-forbidden, exchange excited f-f transitions are found to characterize the Electron-Energy-Loss Spectra (EELS) of rare-earth metals taken at low primary energy. The transitions are identified by comparison with optical and photoemission data. The intensities of the f-f peaks and of the plasmon peak resonate when the primary energy is close to the 4d binding energy E4d.
