| Outline of Final Research Achievements |
The main purpose of this study is to develop a method to determine the phase of molecular orbitals by means of interference phenomena in inelastic electron scattering processes. To this end, electron momentum spectroscopy experiments and electron energy loss spectroscopy experiments were performed for the nonbonding orbitals of simple molecules like SF6, which are each constructed from the 2p atomic orbitals (AOs) on the constituting atoms. A detailed analysis of the results shows that the interference patterns afford a rare opportunity to experimentally clarify symmetries of the MOs. It is also demonstrated that they provide information about the spatial orientation of the constituent AOs. Furthermore, vibrational effects on electron momentum profiles and electron scattering cross sections have been investigated.
