Many-body effects in core-level photoemission and core-level photoabsorption are
discussed for rare-earth systems, especially for Ce and La compounds, both in metallic and …

It is well known that crystals of rare-earth salts are often characterized by sharp absorption or
emission lines. Theunderstanding of the precise nature of these lines, ie, their spectroscopic …

By use of the exact solution for the Anderson model with a filled valence band for finite
system, the core photoabsorption spectra of the mixed valence CeO 2 are discussed. The …

The electronic ground states and core-hole and valence-hole excited states of so-called
tetravalent and mixed-valence Ce compounds are studied taking into account strong …

The consequences of the degeneracy between configurations with different populations of
atomiclike f states are studied systematically for a number of light rare-earth materials (Ba …

Possible applications of high coercitivity rare earth (RE) permanent magnets (eg SmCos),
possible use of RE bubble materials in computer technology and of RE alloys for hydrogen …

Here we report the interpretation of all spectral features of Ce L 3 x-ray-absorption near-
edge structure (XANES) of CeO 2 over a 40 eV range. The local partial unoccupied density …

The electronic ground state, core-hole states, and valence-hole states of Ce O 2 are studied
taking into account strong correlation among the 4 f electrons. The ground state is …

Publisher Summary The chapter discusses X-ray absorption and emission spectra. This
chapter is dedicated to a review of modern X-ray absorption spectroscopy of lanthanides, in …

The current status of theoretical and experimental research concerning valence change
transitions and the intermediate or mixed valence state in rare earth and actinide crystalline …
