Valance-Band photoemission intensities in thorium dioxide

Resonant photoemission spectra of the O 2 p-derived valence band of insulating ThO 2 are compared to linear muffin-tin orbital (LMTO) density-of-state (DOS) and XPS intensity calculations. At Th 5 d corelevel threshold energies (85 ⩽ hv ⩽ 120 eV), resonance is greatest at the bottom of the O 2 p ban...

Description
Summary:Resonant photoemission spectra of the O 2 p-derived valence band of insulating ThO 2 are compared to linear muffin-tin orbital (LMTO) density-of-state (DOS) and XPS intensity calculations. At Th 5 d corelevel threshold energies (85 ⩽ hv ⩽ 120 eV), resonance is greatest at the bottom of the O 2 p 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 2 p states and Th 6 d.
