Abstract : The crystal-momentum dependence of the line shapes appearing in photo-excitation from the valence levels of ordered S on Fe(100) has been measured using angle resolved photoelectron spectroscopy. The variation in line shape with k is a consequence of the hybridization of the energy bands of the 2-D overlayer with the 3-D solid. This observation, predicted theoretically by Liebsch, yields detailed information about the bonding interactions of ordered chemisorption systems. (Author)
