Double polarization photoelectron spectroscopy using circularly polarized x-rays and true spin detection has been performed using the 2p core levels of ultrathin films of Fe and Co. This includes both the separation into magnetization- and spin-speci

Angle-resolved photoemission experiments have been performed on USb2, and very narrow quasiparticle peaks have been observed in a band, which local spin-density approximation (LSDA) predicts to osculate the Fermi energy. The observed band is found to

The electronic structure of select Pu materials is examined by means of photoemission (PES) and model calculations. We present the first photoemission results and electronic structure calculations for the material PuIn3. Results for Pu materials, inc

We present the photoemission results of two layered tetragonal compounds, the anti-ferromagnet UAsSe and ferromagnet USb 2 . We observed intriguing electronic structure for both UAsSe and USb 2 , in which relatively dispersive and narrow 5f bands are

We carried out high resolution photoelectron spectroscopy (PES) studies on a gallium stabilized δ-phase plutonium sample cleaned by laser ablation and gas dosed with O 2 . The measurements were made at a sample temperature of 77 K with an overall in

The structure of a 12 ML ultra-thin film of Fe on Cu(1 1 1) has been investigated using medium-energy ion scattering. The as-deposited film was found to be poorly ordered with a mean square static displacement of 0.23 A However, the order was improve

The interaction of Mn with the Cu(1 1 1) surface has been investigated using the normal incidence X-ray standing wave (NIXSW) method. Analysis of the NIXSW was complicated by the apparent large shift in position of many layers of the Cu atoms relativ

We present a theoretical model, the mixed-level model, aiming at describing metals with very complex, strongly correlated, electronic structures. As a demonstration, it is applied to the electronic structure of δ-Pu. The model reproduces the electro
