PHOTO-HOLE LIFETIMES OF ADSORBATE-BANDS AT THE CU(110)(2X1)O SURFACE

Using high-resolution angle-resolved ultraviolet photoelectron spectro scopy we have investigated the occupied antibonding adsorbate bands of the Cu(110)(2 x 1)O surface. In this study we focused on the influenc e of sample temperature on binding energies and linewidths, respective ly. From the analysis of these data we extract information on electron -phonon and hole-phonon interactions, as well as the lifetimes of anti bonding photohole states located in the added-row Cu-O-Cu-O chains.
