We present calculations on energy- and time-resolved two-photon photoemission\nspectra of images states in Cu(100) and Cu(111) surfaces. The surface is\nmodeled by a 1D effective potential and the states are propagated within a\nreal-space, real-time method. To obtain the energy resolved spectra we employ a\ngeometrical approach based on a subdivision of space into two regions. We treat\nelectronic inelastic effects by taking into account the scattering rates\ncalculated within a GW scheme. To get further insight into the decaying\nmechanism we have also studied the effect of the variation of the classical\nHartree potential during the excitation. This effect turns out to be small.\n
