Research Abstract

本研究では、日本原子力研究開発機構・高崎研のTIARAの重イオンパルスを活用し、イオンビーム照射によるシンチレーターの発光を分析光として利用した新規な時間分解吸収分光法を考案し、数少ないイオンビームで測定が可能な重イオンパルスラジオリシスの開発を行った。ナノ秒時間領域で中間活性種の過渡吸収の測定により、重イオンビーム励起によって生成されるカチオンラジカル、電子、励起状態分子など初期の短寿命中間活性種の挙動を明らかにし、化学反応機構の出発点となる初期過程の解明を行った。また、低LETの電子ビーム誘起現象との比較により、重イオンビームの高密度励起効果の研究を行った
