• Overview of the research

  量子ビームを用いた原子衝突物理，原子分子光（AMO）科学，イオンビーム分析に関する実験的研究を行っている． 量子ビーム科学は，現代における放射線科学である． 放射線と物質の相互作用の研究は100年以上の長い歴史があるが，昨今の量子ビーム技術の発展や，その周辺の計測技術および計算環境の高度化により， 基礎・応用研究の両面で新たな飛躍の機運が高まっている．私は特に，加速器からの高エネルギーイオンビームを利用した実験を中心に，原子・分子・クラスター・表面との衝突相互作用の研究を進めている． 具体的には，生体分子を含む様々な気相の孤立多原子分子や，真空内微小液滴を標的とした実験装置を開発し，MeV重イオンなどの量子ビームが誘起する複雑な分子反応過程の解明を目指している． また最近では，イオンビーム分析を用いた応用研究にも参画している． 従来にはない新奇な実験技術や測定システムを構築するというスタイルで，未知の衝突反応現象の探索やそのメカニズムの解明，新たな分析技術の開発を目指している．
