We plan to upgrade the U5U undulator beamline at Brookhaven with a 4-grating 3.5 m SGM (spherical-grating-monochromator) system offering the following enhancements in performance: (1) Improved imaging especially at the sample; (2) Small “expendable

The physics of the soft-X-ray whispering gallery is outlined with emphasis on the delivery of circularly-polarized radiation in the photon energy range h ω = 10–180 eV . Calculations of the relevant figure of merit TP2 (T = transmission, P = polar

Expressions are derived for the relationship between the measured linewidths in angle-resolved valence-band photoemission spectra and the lifetimes of the photoelectron and photohole. The expressions are different for the energy-distribution curve (E

Efficient differentiation between the left and right circular polarization of soft x-ray synchrotron radiation is achievable by doubling the number of prefocusing mirrors in a Dragon monochromator. The design also permits easy reversion to convention

The combination of spin‐polarization detection with core‐level photoemission to give spin‐polarized electron spectroscopy for chemical analysis provides new information on the oxidation of an iron surface. During the initial stage of oxidation

It is argued that the inverse photoemission features on Au(110)(1 × 2) attributed recently to surface umklapp effects are in fact surface states intrinsic to the unreconstructed (1 × 1) surface.

Spin-polarized photoemission experiments on expitaxial Ag overlayers on Fe(001) have shown that a minority-spin surface state of the bare substrate evolves into an interface state, moves to higher energies, and crosses the Fermi level ${\mathit{E}}_{

Photoemission data in which the signal from the first atomic layer is well resolved from that of the bulk are used to determine accurately the kinetic-energy dependence of the inelastic-electron mean free path in the alkali metals. At the higher kine

A tight-binding analysis of soft-x-ray-absorption and magnetic-circular-dichroism (MCD) spectra on Ni at the 2p\ensuremath{\rightarrow}3d thresholds yields values for the valence spin-orbit parameter and exchange splitting which are, respectively, la
