摘要: We report measurements of the temporal dynamics valence band photoemission from magnesium (0001) surface across resonance $\overline{\mathrm{\ensuremath{\Gamma}}}$ state at 134 eV and link them to observations high-resolution synchrotron numerical calculations time-dependent Schr\"odinger equation using an effective single-electron model potential. observe a decrease in time delay between delocalized states localized core orbitals on resonance. Our approach rigorously excitation energy-resolved conventional steady-state with attosecond streaking spectroscopy reveals connection energy-space properties bound electronic fundamental excitations underlying photoelectric effect.
