Abstract

Thin-film energy-band determinations of a surface-state-surface-resonance band in Al(001) are found to account completely for and clarify the new angle-resolved photoemission observations of Gartland and Slagsvold. The transition from a true surface state to a surface resonance is explained in terms of a mechanism in nearly-free-electron metals for the formation of surface resonances in "partial" Bragg-reflection bulk energy gaps.
