    Research

    Toward understanding of basic features and chemical reactions in the nature, we set up different experimental apparatuses with state-of-the art techniques. Recently, we focus on the chemical dynamics related to electron/nuclear spin, molecular chirality, and quantum tunneling.

    Dissociative Electron Attachment

    since 2012

    Dissociative electron attachment (DEA) of molecular AB, e- + AB -> A + B-, is an important process in the interstellar space and planetary atmospheres. Our experimental DEA study started in 2012, rebuilt the apparatus in 2017 and now update in 2026. In the new apparatus, a pump (laser pulse) -probe (low-energy electron pulse) method is introduced for the DEA dynamics of excited / aligned molecules.

    (2012~2016) (2017~2025)

    Ion-Molecule Reaction

    since 2017

    Ion-molecule reaction is another important process in interstellar space and planet atmospheres. In 2017, we set up an ion velocity-map-imaging apparatus to investigate the stereodynamics of ion-molecule reactions. Combined with femtosecond lasers, we are developing a new apparatus for the ultrafast dynamics study, particularly, the chiral reactions.

    (2017-2025)

    Liquid & Surface

    since 2018

    To study the electron-induced reactions in liquid and interface (consisting of the outermost layer and subsurface), we established a conceptually new method 'time-delayed mass spectrometry'. Using this method, the molecular orientations both on the outermost layer and in the subsurface were revealed; more importantly, in situ existence of molecular clusters and electron-induced synthesis (including DEA) in the liquid surface were confirmed for the first time. The products can be desorbed with the assistance of infrared picosecond laser pulses. This pump (electron)-probe (infrared laser) technique will be used for the study of liquid interfacial chemical dynamics, but now the project is suspended. We also successfully observed ultraviolet high-order harmonics generations from liquid sheets and the gas-phase methane in a tube.
