摘要
We study the role of electron-electron correlation in the ground state of Ne, as well as in photoionization dynamics induced by an attosecond XUV pulse. For a selection of central photon energies around 100 eV, we find that while the mean-field time-dependent Hartree-Fock method provides qualitatively correct results for the total ionization yield, the photoionization cross section, the photoelectron momentum distribution, as well as for the time delay in photoionization, electron-electron correlation is important for a quantitative description of these quantities.
