Outline of Final Research Achievements |
Time-resolved photoelectron spectroscopy (TRPES) can serve as a powerful tool for investigating non-radiative dynamics and photochemistry. Recently we developed a laser system to generate single-order vacuum-VUV radiation at 90 nm (hv = 14 eV), and integrated it with a TRPES apparatus.

Academic Significance and Societal Importance of the Research Achievements |
本研究で得られた15fsというパルス幅は、これまで実現されたサブmJ深紫外パルスの中で最も短いものである。本課題が研究対象とした超高速非断熱遷移は、紫外線による光損傷、光合成、視覚の制御を司るレチナールの異性化等、様々な光化学反応において見られる普遍的な現象である。
