Abstract
Angle-resolved photoemission studies of H on the Nb(110) surface show H-related structures with photon-energy-dependent binding energies in normal emission. The development of these features with exposure is pressure and energy dependent. These properties, together with a reversible temperature-dependent amplitude, are attributed to an initial adsorption regime followed by absorption of hydrogen into the near-surface substrate layers of Nb.
