This chapter provides data of photoemission and inverse photoemission of gold (Au). The Au(100) and (110) surfaces are reconstructed in their equilibrium state at room temperature. Au( 100) gives rise to a buckled pseudo-hexagonal surface overlayer characterized by a complex LEED pattern: Au(100) (hex). In both cases, Au(100) and Au(110), the unreconstructed surfaces can be prepared at elevated sample temperatures. Surface core level shifts of the Au 4f_7/2 level to lower binding energy has been observed on Au(100), Au(110) and Au(111). High resolution photoemission spectra for Au(100), Au(111), Au(112) and normal emission photoelectron spectra for Au(111) are recorded. Projection of the bulk band structure onto the (111) surface Brillouin zone and (110) surface Brillouin zone are graphically illustrated. Further, inverse photoemission spectra are recorded from Au(100), Au(110) and Au(111). High resolution soft X-ray photoemission spectra are recorded from the 4f_{7 / 2} core level of Au(111), Au(110) and Au(100).
