Outline of Final Research Achievements |
We developed two methods for detecting solvated electrons in liquids interacting with plasmas. One was the CTTS (Charge Transfer to Solvent) transition. This is a kind of photo-excited process to produce solvated electrons, and we can examine the reaction frequency of solvated electrons in liquids interacting with plasmas. The other method was the production of free electrons by laser-induced desolvation. The free electrons produced by the desolvation were transported to and detected in the plasma. We have shown experimentally that these two methods works effectively for investigating solvated electrons in liquids interacting with plasmas.

Academic Significance and Societal Importance of the Research Achievements |
プラズマと相互作用する液体中に存在する溶媒和電子は,プラズマ誘起反応に決定的な影響を与えると考えられるにもかかわらず,本研究以前にはそれを研究するための実験技術がほとんどなく,手出しできない研究課題となっていた。本研究で開発した方法により,プラズマと相互作用する液体中に存在する溶媒和電子を実験的に研究することができるようになった。今後,本研究で開発した方法が研究コミュニティに普及すれば,プラズマと液体の相互作用に関する研究が進展すると考えられる。
