摘要：
Occupied and unoccupied electronic states formed by adsorption of benzene on Cu(110) have been measured by one- and two-photon photoemission spectroscopy. An occupied state found at -2.2 eV relative to the Fermi level (Er.) was not dispersive either along the surface normal nor parallel directions. An unoccupied state was found at 0.5 eV above E-F. The lifetime of electrons in the state was about 120 fs. The occupied and unoccupied states are formed by hybridization of pi-electrons with large contributions of metal electrons.
