Abstract

Angle-resolved photoemission spectroscopy utilizing synchrotron radiation has been used to study the electronic states of the Ni(110)(1×2)-H reconstructed surface at 80 K. An H-induced state, split off from the Ni bulk bands, is found at 9.0 eV below the Fermi energy at. This H split-off state disperses upwards by 3.1 eV with k? in the [110] (X) azimuth whereas it exhibits no measurable dispersion in the [001] (Y) azimuth. The intrinsic Ni(110) surface states were not identified along the line in k space from to X. It was found that the 3d-like 1-symmetry bulk states at 23 eV at are markedly reduced by H adsorption, indicating that the Ni 3d (1) states participate in the bonding.
