Аннотация:
The electron-emission spectra of atomic Eu and Sm after resonant 4d to 4f excitation by synchrotron radiation have been measured. Energy levels have been calculated using a multiconfiguration Dirac-Fock code. Strong enhancement of the resonant structures has been found at the resonant excitations below the giant resonance. The present vapour-phase results are in good agreement with the corresponding solid-state results, especially for Eu.
