Abstract
The photoelectric current is calculated on the basis of the Green's fu nction matching method. Peak widths and intensities of bulk and surfac e states are studied in dependence on electron and hole lifetimes. For Cu(111) it is shown that the ratio of peak intensities of both types of states yield information on electron inverse lifetime which can par ticularly be used for very low energies (<10 eV), where the peak width analysis for studying lifetimes fails.
