Ultraviolet photoelectron spectra of mass-selected copper clusters: Evolution of the 3 d band
摘要：
Ultraviolet photoelectron spectra (UPS) have been measured for bare unsupported copper clusters in the 1–410 atom size range as mass selected from a supersonic, negatively charged, cluster ion beam. Using an F 2 excimer laser at 7.9 eV, the UPS patterns display the evolution of the 3 d band structure as a function of cluster size. Clusters larger than a few atoms were found to display an increasingly sharp feature at the onset of the 3 d band similar to that seen for bulk copper UPS at low photon energies, suggesting that these larger clusters may already be crystalline.
