An electron momentum spectroscopy (EMS) study of the outer valence orbitals of N2O is reported. The experiments were performed at impact energies of 1000, 1200, 1600 and 1800eV by using a recently developed multichannel (e, 2e) spectrometer. The experimental momentum profiles are compared with each other to examine their impact energy dependence. The results are used for comparisons with Hartree-Fock (HF) and density functional theory (DFT) calculations using various basis sets. The HF and DFT calculations with large basis sets are in very good agreement with the measured electron momentum profiles. Experimental spectroscopic factors for several transitions are reported.
