| Abstract: | New high resolution ultraviolet photoemission energy distributions (EDCs) from copper are found to agree best with the calculations of Williams et al., using the Chodorow potential, if an energy dependent shift is made between the experimental and calculated EDCs. It is argued that this shift is most probably due to an energy dependent self energy as discussed by Lundqvist and others. |
