Valence - Band Photoemission Intensities in Thorium Dioxide
نویسنده
چکیده
Resonant photoemission spectra of the O 2p-derived valence band of insulating ThO2 are compared to linear muffin-tin orbital (LMTO) density-of-state (DOS) and XPS intensity calculations. At Th 5d corelevel threshold energies (85 ~< hv <<. 120eV), resonance is greatest at the bottom of the O 2p band where calculated p/d hybrid states are greatest; p / f hybrid content is weak by comparison. We conclude that the dominant hybridization is between O 2p states and Th 6d.

Oscillations in the valence-band photoemission spectrum of the heterofullerene C59N: A photoelectron interference phenomenon
The intensities of the two strongest low-binding energy features in the valence-band photoemission spectra of C59N have been observed to oscillate as the photon energy of the exciting radiation is varied. The maxima in the intensity ratio of the two peaks occur at the same photon energies as the maxima in the intensity ratios of the highest occupied molecular orbitals to next highest occupied m...
متن کاملValence transition of YbInCu4 observed in hard X-ray photoemission spectra.
Yb 3d and valence-band photoemission spectra of the first-order valence-transition compound YbInCu4 have been measured with hard x ray at an excitation energy of 5.95 keV. Abrupt changes are clearly observed in both spectra around the transition temperature T(V)=42 K, in comparison with ultraviolet and soft x-ray photoemission (VUV-PES and SX-PES) spectra. From the Yb 3d spectra, the Yb valence...
متن کاملSpin-resolved photoemission of valence-band satellites of Ni
Spin-resolved photoemission spectra of 6-, 9-, and 13-eV satellites of the ferromagnetic Ni valence band are reported. The spin polarization of the valence-band satellites and their photon energy dependence are interpreted by the multiplet configuration of 3d and 3d final states. This implies the localization of a photoexcited final state reflecting the strong electron correlation in Ni. @S0163...
متن کاملElectronic and bonding structures of B-C-N thin films investigated by x-ray absorption and photoemission spectroscopy
X-ray absorption near-edge structure ~XANES! and valence-band photoelectron spectroscopy ~PES! were used to investigate the electronic and bonding structures of B-C-N thin films. The intensities of the sp-bonded features in the C K-edge XANES spectra are found to generally decrease as the C concentration increases, whereas the intensities of the sp-bonded features in the spectra of N K-edge XAN...
متن کاملSite-specific valence-band photoemission study of a-Fe2O3
We have measured the site-specific valence electronic structure of a-Fe2O3 by using a spatially modulated x-ray standing wave as the excitation source for photoemission. Contributions to the valence-band density of states from oxygen and iron ions are separated by this method. Both a bonding and nonbonding state originating from oxygen ions are obtained. The valence densities of states from iro...
