Abstract

Soft x-ray emission near the 3d threshold of La is studied with synchrotron radiation. At excitation energies above the (Formula presented) edge we observe Coster-Kronig enhanced fluorescence that refills the 3d hole via 5p and 4f electrons. We find a new delayed onset of the fluorescence as the 7.5-eV inelastic scattering evolves into 3d-4f emission about 8 eV above the absorption threshold, which we attribute to the energy required to produce a charge-transfer hole. The 16.3-eV Raman-scattering loss is due to a net transition of a 5p electron into a 4f orbit. The results are compared with our calculations. © 1998 The American Physical Society.
