The electronic state of the hydrogen-adsorbed Cr(110) surface at 80 K has been investigated using angle-resolved photoemission spectroscopy. We observed a p(2×2) low-energy electron-diffraction pattern at 1/4 2 L, and a streaked (1×1) pattern along the [11»0] azimuth at above 10 L. The photoemission results show that for the p(2×2) phase an H 1sderived state, having a nearly constant binding energy of 1/4 5.5 eV below the Fermi level, is observed in the outer part of the surface Brillouin zone, that is, outside the Cr s-p band projections. [Here 1 langmuir (L)10-6 Torr sec.] On the other hand, for the streaked (1×1) phase, an H 1sderived state, split off from the Cr bulk bands, is found at the binding energy of 7.8 eV at » and shows considerable dispersion of 1/4 2.8 eV in the  azimuth being consistent with the periodicity of the substrate structure. In addition, a H-induced surface state is found at 2.5 eV at » for both phases. The nature of the Cr-H chemisorption bond is discussed.
