N2 - Abstract: Interference effects on electron momentum density distributions have been studied usingelectron momentum spectroscopy (EMS) for the three outermost orbitals ofCCl4, which areconstructed from the Cl 3p nonbonding atomic orbitals. The EMS experiment was conducted inthe symmetric noncoplanar geometry at an incident electron energy of 2.0 keV. Interferencepattern has then been obtained by dividing the experimental data bydistorted-wave-Born-approximation cross section for an isolated Cl 3p atomic orbital. Acomparison with the result of our earlier study on CF4 [N. Watanabe, X.-J. Chen, M.Takahashi, Phys. Rev. Lett. 108, 173201 (2012)] has demonstrated that theperiod of the interference pattern reflects the internuclear distance between theconstituent halogen atoms. Furthermore, the present result strongly suggests thatdistorted-wave effects lead to partial destruction of the interference forCCl4 at largemomentum.
