The electronic structure of hydrogen adsorbed on Ni(110) at 150 K has
been studied using angle-resolved photoelectron spectroscopy with mono
chromatized He I alpha radiation. At a saturation coverage of 1.5 mono
layers, we observe a general shift of the spectral weight away from th
e Fermi level to higher binding energies indicating the hybridization
of hydrogen levels with metal d states. Along selected Ni 3d bands the
intensity shift is obvious whereas other bands remain unchanged. In a
ddition, contrary to previous observations, a hydrogen induced state i
s visible at a binding energy of roughly 1.2 eV. [S0163-1829(98)50244-
