Ultrafast hydrogen migration

利用先进的超短脉冲激光系统的符合动量成像方法，研究了强激光中氢的超快迁移动力学。提出了一种新的时间分辨电子衍射方法来跟踪超快氢气运动，并首次观测到了超短脉冲激光场诱导的电子散射信号，验证了该方法的可行性。此外，还建立了描述超快氢迁移的电子-质子系统关联动力学的量子动力学理论。

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.
