    Resonant photoemission in highly localized versus weakly localized solids (1994)

    Notes: Abstract We report on comparative study of angle-resolved photoelectron spectra of Ni metal and CeGd at theM III andN IV,V soft-x-ray absorption threshold, respectively. OnM III resonance, the valence-band photoemission (PE) intensity of Ni follows a cos2-behavior, while the intensity of the 6-eV satellite is independent of the angle of emission relative to the E-vector of the incoming beam. On the other hand, the 4f Ce PE signal behaves ∝ cos2 onN IV,V resonance. This clearly shows that the resonant enhancement of the 6-eV PE satellite of Ni is mainly caused by an incoherent Auger decay and cannot be described as a resonant PE process.

    Resonant photoemission study ofK-derived valence-band states in K X C60 (1993)

    Notes: Abstract The electronic structure of K-doped C60 was investigated by photoemission (PE) and X-ray absorption near-edge structure (XANES) studies at the C-1s and K-2p thresholds. In addition, information on the local K-derived partial density of states in superconducting K3C60 was obtained by resonant PE at the K-2p 1/2 threshold. The experimental observations support a complete charge transfer from K to C60 and we clearly observe a finite density of states atE F . From resonant PE, occupied states with K-p, d character could be identified in the binding-energy region from 1.5 to 8 eV below, but not directly at the Fermi level. This partial-density-of-states structure agrees well with the results of our band-structure calculations based on the local-density approximation.

    Resonant photoemission at the 2p thresholds of Fe, Co, and Ni metal (1994)
    Springer

    Notes: Abstract Resonant photoemission studies have been performed at the 2p soft-x-ray absorption thresholds of Fe, Co, and Ni metal. At resonance, the photoelectron intensity exhibits a strong enhancement in the region of the two-hole satellites, which is shown, however, to be mostly due to an incoherent superposition of a photoemission signal with a more intense signal from anL 3 M 4,5 M 4,5 Coster-Kronig decay of the core-ionized state. The resonant enhancement of the valence-band photoemission satellite in Ni metal amounts to a factor of ≃12. In contrast, no photoemission satellites are observed for Fe and Co metal.
