ResumoUsing time-resolved two-photon photoemission, we show that the inelastic lifetime τee of optically excited electrons of copper depends crucially on whether the electron is excited by an intraband or an interband transition. These results indicate clearly that τee of photoexcited electrons is determined not only by the available phase space for the inelastic scattering process, but also depends on the initial state of the excited electron.
