| Outline of Final Research Achievements |
In this study, aiming at experimentally investigating the origin of intermolecular interaction in terms of electronic structure, we have broadened the applicability of electron momentum spectroscopy (EMS) that enables us to study electron momentum distribution of individual molecular orbitals by using electron Compton scattering. As a result, we have developed a highly-sensitive apparatus whose correction efficiency is estimated to be two orders of magnitude higher than that of the existing apparatus of same size. In addition, it has become possible to improve the experimental resolution of electron binding energy by a factor of two. Furthermore, the apparatus has been successfully applied to EMS studies of core orbitals. In parallel, theoretical analysis to extract information on reaction intermediates from time-resolved EMS data has been developed. These achievements form the basis for making interaction-orbital imaging of atomic and molecular clusters feasible.
