Abstract

We have identified occupied surface-state bands from angle-resolved photoelectron energy distribution curves of Au(112), Au(100), and Au(110), which are located in $\mathrm{sp}$ gaps of the projected bulk band structure. An approximate criterion for their possible experimental existence is given.
