The magnetic phase transitions for Gd(0 0 0 1) grown on W(1 1 0) - a bulk transition at 293 K and a surface transition about 85 K above this - are found to influence the energy separation of the Gd 5s and 4s core-photoelectron doublets. The 5s double

We have studied the kinetics of the low-pressure adsorption of oxygen on W(110) via time- and chemical-state-resolved photoelectron spectroscopy (PS) and diffraction (PD). Using high-brightness third-generation synchrotron radiation from the Advanced

We have measured the circular dichroism in angular distributions (CDAD) of W 4f emission from a stable one-monolayer structure of oxygen on W(110) that is locally (1×1) in character. Photoelectrons were excited at kinetic energies of approximately 2

The authors have studied the atomic structure of the clean W(110) surface by means of site-resolved scanned-angle W4f{sub 7/2} photoelectron diffraction (PD) data obtained over nearly the full 2{pi} solid angle above the surface. Prior to the availab

The local atomic geometry of oxygen adsorbed in a stable one monolayer (1×1) structure on W(110) has been determined for the first time from full solid angle site-resolved photoelectron diffraction (PD). This structure also exhibits an additional (1

Spin-polarized photoelectron diffraction (SPPD) has been used previously by the authors group to study two antiferromagnetic surfaces (KMnF{sub 3} (011) and MnO(001)) - these measurements provided evidence of a surface and/or short-range-order magnet

We have used high- and low-energy X-ray photoelectron diffraction to determine the structure of formate adsorbed on TiO 2 (110). Formate binds to the surface through both oxygens to pairs of neighboring Ti 4+ cations oriented along [001] to form a 2

Full-solid-angle and site-specific photoelectron diffraction data have been obtained from interface W atoms just beneath (1{times}1) Fe and (7{times}14) Gd monolayers on W(110) by utilizing the core level shift in the W f4{sub 7/2} spectrum. A compar
