Angle-Resolved Resonant Photoemission as a Probe of Spatial Localization and Character of Electron States

Abstract

Resonant photoemission (PE) in the angle-resolved mode is proposed as a method to determine the spatial localization and the angular momentum character of valence band states from on-resonance PE signals across the Brillouin zone. This technique is applied to study ordered films of La metal. The obtained experimental data agree well with the results of band-structure calculations and related eigenvector analysis.
