Resonant-photoemission study of Fe(100)

Abstract
Resonant photoemission of Fe(100) in the vicinity of the 3p-electron excitation threshold (53 eV) has been studied as a function of emission angle and photon energy. The resonant part in the energy distributions resembles closely convolutions of the spin-split valence-band density of states of Fe, centered at constant kinetic energy. This demonstrates that Auger decay dominates the resonant feature. At the binding energy of Γ25 the photocurrent is virtually independent of photon energy.
