Abstract
Resonant photoemission has provided important new means to study the properties of the 4f electron states in the light lanthanides. These investigations have revealed unexpectedly complex 4f spectral shapes. This has led to new insight into the problem of the 4f systems. Some recent results for Ce are reviewed and it is shown how these disprove the previously accepted promotional model for Ce. The results are briefly discussed in terms off-hybridization and possible band formation. Some expected future experimental developments are also discussed.
