| Outline of Final Research Achievements |
Charged-particle imaging for gas-phase molecular systems is one of the powerful tools to study molecular dynamics of interest. In a typical imaging method, however, there have been several dynamics which cannot be observed due to experimental limitations. In this study, to overcome difficulties in existing methods, we developed a new spatial slice imaging apparatus. In our method, only photoelectrons/ions in the polarization plane of laser pulses are directly selected by a mechanical slit and then imaged. We applied our method to laser-driven rotational wavepacket, and (the square of) rotational wavefunctions in electronic exited state molecules. In the observed image, wave, quantum nature of dynamics can be clearly seen. We believe our method opened a new way to probe the molecular dynamics.
