Abstract

The observation of resonant photoemission at shape resonance energy in Sb(0001) is reported. When the photon energy was tuned to the 4d → εf transition region of the Sb shape resonance (∼90 eV), a Fano-like profile was observed in the photoelectron cross-section from the half-filled 5p valence orbitals. Two new, significant features appeared at photon energies above the 4d threshold: one in the gap between the filled 5s2 and half-filled 5p bands, and the other at the Fermi level. The former is attributed to final state mixing in the autoionization decay of the εf transition state, and the latter to a two-photon photoionization process directly from the εf transition state.
