Soft x-ray emission near the {ital 3d} threshold of La is studied with synchrotron radiation. At excitation energies above the M{sub IV} edge we observe Coster-Kronig enhanced fluorescence that refills the {ital 3d} hole via {ital 5p} and {ital 4f} electrons. We find a new delayed onset of the fluorescence as the 7.5-eV inelastic scattering evolves into {ital 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 {ital 5p} electron into a {ital 4f} orbit. The results are compared with our calculations. {copyright} {ital 1998} {ital The American Physical Society}
