Outline of Research at the Start

化学反応や分子機能を司る電子のダイナミクスを複雑な解析を経ることなく可視化することを目的として,強レーザー場における「トンネルイオン化」を利用した新規手法の開拓を行う。特にトンネル電子の運動量分布に着目し,これを分子座標系で3次元計測することで,実時間で電子ダイナミクスを直接観測する新しい反応イメージング法の基盤を確立する。

Outline of Final Research Achievements

To understand tunneling ionization of molecules, an electron-ion coincidence measurement system using a high-repetition rate laser was constructed. It was shown that the characteristics of the highest-occupied molecular orbital (HOMO) of hydrogen molecule can be read out from the three-dimensional torus-like structure of tunneling electrons in the molecular frame. On the other hand, the application to tetrafluoromethane revealed that the recoil-frame angular distribution has a dependence of the helicity of the circularly polarized laser fields, due to the correlation between ionization and dissociation. A new method utilizing an auxiliary dissociation pulse was developed to disentangle the correlation, and applied successfully to oxygen molecule. In addition, adiabatic theory for diatomic molecules incorporating the molecular vibration was developed.

Academic Significance and Societal Importance of the Research Achievements

本研究では,強レーザー場トンネルイオン化によって生成した電子の分子座標系分布の迅速計測を実現し,2原子分子や多原子分子についてトンネル電子運動量から,最外殻電子の情報がどのように読み取れるかを明らかにした。またそこで見出されたイオン化と解離の相関に由来する問題を解決するための,新たな手法の開拓を行った。分子の性質を司る重要な役割を担う,弱く束縛された電子を可視化することは分子の反応や機能を理解する上で重要である。本研究での結果は,電子のダイナミクスを複雑な解析を経ることなく可視化するための手法としてのトンネルイオン化イメージングの基盤を構築する上で重要な成果である。
