Valence-Band Photoemission In La And Pr: Connections With The Ce Problem, David Michael Wieliczka, C. G. Olson, David W. Lynch Jun 1984

Valence-Band Photoemission In La And Pr: Connections With The Ce Problem, David Michael Wieliczka, C. G. Olson, David W. Lynch

Physics and Astronomy Publications

Energy distribution curves from La and Pr were taken from 32 to 80 eV photon energies. Above 50 eV the valence-band photoemission in La is very weak, implying that previous studies of Ce have underemphasized the 4f contributions. Pr exhibits two peaks attributable to 4f electrons, similar to the structures in Ce.


High-Resolution Photoemission Study Of Γ- And Α-Cerium, David Michael Wieliczka, C. G. Olson, David W. Lynch Mar 1984

High-Resolution Photoemission Study Of Γ- And Α-Cerium, David Michael Wieliczka, C. G. Olson, David W. Lynch

Physics and Astronomy Publications

High-resolution photoemission studies on the α and γ phases of cerium show changes in the binding energies of the two4f-related features. The location of the two 4f-related features in the γ phase are at -0.2 and -2.0 eV, while in the αphase these features are located at the Fermi level and -2.1 eV. These results are a direct test of the theories proposed to explain the presence of the two features.
