(e,2e) spectrometer. The impact energy was 1200eV plus binding energy (i.e. 1206 to 1232 eV) and symmetric non-coplanar kinematics was employed. The inner-and outer-valence energy spectrum is in agreement with published Photoelectron data. The experimental momentum profiles have been compared with calculations obtained using Hartree-Fock method with the minimum basis set and a high-level basis set, and also using density functional theory (DFT) density methods with a high level basis set. The agreement hetween theory and experiment for shape of orbital electron momentum distributions is generallygood.展开更多

We use non-birming mode to get the Ar3p、 3s and 3s satellites binding energy spectra separately. The experAnental results is well consistent with the available theoretical results.展开更多

The impact energy was 1200 eV plus binding energy (i. e. 1205 to 1230 eV) and symmetric non-coplanar kinematics was employed. The experimental momentum Profiles have been compared with those calculated using Hartree -Fock method and Density Funchon Theory.展开更多
