摘　　要：We report the experimental and theoretical investigation of the complete valence shell binding energy spectra and momentum profiles of naphthalene (C 10 H 8),using our high resolution electron momentum spectrometer,at impact energies of 1500 eV and 600 eV.The observed momentum profiles were compared with the Hartree-Fock (HF) and density functional theory (DFT) calculations,and the binding energy spectrum was compared with the Outer valence Green's function (OVGF) calculations.The impact energy dependent discrepancy between observed momentum distributions and calculations under the plane wave impulse approximation was ascribed to the distorted wave effects.We report the experimental and theoretical investigation of the complete valence shell binding energy spectra and momentum profiles of naphthalene （C10H8）, using our high resolution electron momentum spectrometer, at impact energies of 1500 eV and 600 eV. The observed momentum profiles were compared with the Hartree-Fock （HF） and density functional theory （DFT） calculations, and the binding energy spectrum was compared with the Outer valence Green＇s function （OVGF） calculations. The impact energy dependent discrepancy between observed momentum distributions and calculations under the plane wave impulse approximation was ascribed to the distorted wave effects.
