Time-and-state resolved spectroscopy, diffraction, and circular dichroism in core photoelectron emission from clean and oxygen-covered W(110)
- Univ. of California, Berkeley, CA (United States)
Several aspects of core-level photoelectron emission fi-om solid surfaces as excited by high-brightness variable-polarization synchrotrons radiation have been studied with a new beamline and experimental station at the Advanced Light Source in Berkeley. These include: resolution of different chemical states and site types via high-resolution photoelectron spectroscopy (PS), the use of state-resolved photoelectron difllaction (PD) to determine local atomic geometries, and the observation and analysis of circular dichroism (CD) effects in photoelectron diffraction. These methods have been applied to clean and oxygen-exposed surfaces of W(110). Full-solid-angle photoelectron diffraction from clean W(110) was measured, with the surface and bulk atoms being clearly resolved.
