Outline of Final Research Achievements

Using novel experimental methods and quantum chemical calculations, we demonstrated various physicochemical processes on the surfaces of cosmic dust analogues, which play an important role in evolution of molecules in space. Notable findings were mode on (1) formation and desorption process of some organic molecules and sulfer- and phosphorous-containing molecules; (2) deuterium fractionation of molecules; (3) nuclear-spin conversion of hydrogen molecules on dust. Furthermore, direct observation of amorphous ice at around 10 K was first successful with cryogenic transmission electron microscope and atomic force microscope.

Academic Significance and Societal Importance of the Research Achievements

星間塵表面での化学物理プロセスは分子雲における初期分子生成・脱離・重水素濃集に主要な役割を果たしているが、その理解には推測による部分が多く残されていた。本研究で、さまざまな表面物質や表面構造、温度で系統的な実験を行うことにより、その理解を格段に深めることができた。また、新たな実験手法の開発や星間塵表面過程への量子化学計算の適用など、これまでの当該分野には無かったアプローチを確立した。
