Abstract
Measurements of high-resolution photoemission-energy distributions have been extended beyond 11.6 eV (LiF-window cutoff) for Cu, Ag, and Au. Surprisingly sharp structure ($\ensuremath{\Delta}E\ensuremath{\sim}0.3$ eV, i.e., resonance $\ensuremath{\Delta}\ensuremath{\equiv}\frac{E}{\ensuremath{\Delta}E}\ensuremath{\simeq}50$) is resolved at these high energies. These new results show $d$-band widths of 3.0, 3.5, and 5.7 eV for Cu, Ag, and Au, respectively, and show dramatic evidence (nonstationary structure and amplitude effects) for direct transitions.
