| Research Abstract |
Dynamics of ultrafast hydrogen migration in intense laser fields was elucidated by a coincidence momentum imaging method with an advanced ultrashort pulsed laser system. A new time-resolved electron diffraction method for tracing ultrafast hydrogen motions was proposed, and electron scattering signals induced by ultrashort pulsed laser fields were observed for the first time, showing the feasibility of the proposed method. Furthermore, quantum dynamics theory for the correlated dynamics of a system consisting of electrons and protons was newly constructed for describing the ultrafast hydrogen migration.
