Surface-state hole decay mechanisms: The Be(0001) surface

First-principle calculations and angle-resolved photoemission experiments are combined to analyze the different contributions to the surface-state hole dynamics at the Be(0001) surface. The computed inelastic electron-electron scattering rate γ is in good agreement with experiment once the electron-...
