Probing the Localization Boundary in 5f electron Systems
ORAL
Abstract
The role of the 5f electrons in the bonding and hybridization for the light actinides is examined. Through use of various types of photoelectron spectroscopy including angle-resolved and resonance techniques, one may define the boundaries for periodic versus central potentials experienced by the outer electrons in actinide materials including UO$_{2}$, PuTe and Pu metal. A comparison with various computational approaches sheds light on the limits of actinide separation in the lattice and bonding to ligand components before one converges on magnetic configurations for materials.
