Abstract : Photoemission studies are used to determine in detail many of the electronic properties of the metals copper and silver over an energy range from the bottom of the d-band to 11.5 ev above the Fermi level. Measurements of the spectral distribution of the quantum yield and of the energy distribution of photoemitted electrons from copper and silver under monochromatic radiation are described and interpreted in terms of the energy-band structure of the metals and the inelastic-scattering mechanisms for energetic electrons. The effects on the photoemission measurements of direct and indirect optical transitions, electron-electron scattering, lifetime broadening, and the Auger process are described. These processes are identified in the experimental data, and used to obtain information on the density of states, the effect of matrix elements, the optical selection rules, the mean free paths for scattering of energetic electrons, and the energy loss per scattering event in both copper and silver.
