We have measured the dispersion of plasmon excitations in polycrystalline Sn, Pb, Cd and Zn using electron energy-loss spectroscopy (EELS) in transmission. These metals show a remarkable deviation of their plasmon behaviour from standard theoretical

Sr2CuO2Cl2. represents a nearly ideal case of a 2-D antiferromagnetic CuO2-plane and thus is of particular interest in the context of the origins of high TC superconductivity. We present high energy spectroscopic results on single crystalline Sr2CuO2

Electron energy-loss spectroscopy in transmission and x-ray photoelectron spectroscopy have been applied to investigate single crystalline Ba2Cu3O4Cl2 to obtain the loss-function along the high symmetry directions of the cuprate plane, the Cu2p and O

The growth mode of H2O adsorption on Ni(110) has been discussed controversially in the past. Hydrogen bonding with dimerisation in the submonolayer regime, followed by a c(2 × 2) bilayer structure with a coverage of one H2O molecule per Ni surface a

The adsorption and decomposition of ethylene oxide on Ni(110) at 95–350 K was investigated by LEED and mainly X-ray and UV photoelectron spectroscopy. Thermal as well as photon-induced decomposition were discovered, with X-rays being about 10 times

The adsorption of ethylene oxide on Ni(110) was studied at 95 K and monolayer coverage by angle-resolved X-ray photoelectron spectroscopy. A slow radiation-induced decomposition at hv = 1486.7 eV to most likely methoxy was noted. The orientation of t

Hydrogen-induced reconstruction of Ni(110) was studied by X-ray photoelectron diffraction (XPD) in the polar angle (θ) scanning mode. The angle-resolved emission of Ni 2p and Ni 3p photoelectrons along the [001] and [110] azimuths for the 1 × 1 and

The ordered adsorbed CO layer of (2 × 1) p2mg symmetry on a Ni(110) surface was studied by X-ray photoelectron diffraction over a polar angle range Θ = ± 85° and for four different azimuthal orientations. Forward scattering enhancement peaks in t
