Outline of Final Research Achievements |
We developed an algorithm for retrieving intramolecular charge distributions from spectral-interferences appearing in energy- and angular-distributions of scattered electrons originating from laser-assisted electron scattering (LAES) processes. We developed a LAES apparatus with high sensitivity and generated ultrashort laser pulses with the duration of 9 fs by the hollow-core-fiber compression method. Furthermore, we developed a computational program for calculating LAES signals induced by broadband ultrashort laser pulses, and showed that observation of spectral-interferences of LAES signals should be feasible. We proposed a new ultrafast electron diffraction method by using single-cycle THz-wave pulses, and demonstrated its performance by numerical simulations.
