The electronic structure of the Cu(100) surface has been calculated self-consistently. The calculation predicts a strong surface-state/surface-resonance band near the top of the bulk Cu $d$ band which has not been observed in previous calculations. The large attenuation in the experimental photoemission signal at the top of the $d$ band which is independent of photon energy and which occurs when various species are chemisorbed on Cu(100) is attributed to disturbance of this surface-state band by the chemisorbed atoms.
