A k-resolved inverse photoemission study was carried out on the low temperature phase of the Ni(110)/(1x2)H-adsorption system. The H-adsorption results in a set of new surface states. Using a simple nearly free electron type model, the surface state energies can be reproduced by adding an attractive potential on the Ni surface and simultaneously increasing the image plane distance from the surface. A bulk transition into the 4sp band observed on clean Ni(110) is modified by H-adsorption, indicating the formation of an sp-derived surface resonance. The measured dispersions are also borne out by the model calculation, although it does not take into account the half periodicity of the reconstructed surface.
