| Outline of Final Research Achievements |
In this study, aiming at visualizing intramolecular atomic motion during a chemical reaction, we have enhanced the potential ability of atomic momentum spectroscopy (AMS) that enables us to investigate momentum distribution of atoms in a molecule by using high-energy electron quasielastic backscattering. As a result, we have successfully developed (1) a highly-sensitive multi-channel apparatus which has increased the signal count rate by nearly three orders of magnitude compared to existing setups, (2) a protocol to extract information about atomic motion due to molecular internal motion from AMS experimental data, (3) an AMS apparatus using an ultrashort pulsed electron gun whose temporal width is short enough to conduct time-resolved spectroscopy. These achievements form the basis for realizing time-resolved version of AMS.
