The present project will study electron-molecule collision processes in gas phase, on surfaces, in cluster environment and in the presence of strong laser fields. A particular focus will be on biologically-relevant molecules, like simple amino acids, for which basic electron attachment mechanisms will be investigated. The effects of laser fields in electron-molecule interaction will also be studied.This research will create new knowledge in the areas connecting collision physics with chemical control, radiobiology and atmospheric science. The research will involve interdisciplinary efforts and collaborations with scientists from other fields. It will train students in broader areas, including several subdisciplines. Examples demonstrating the role of low-energy electrons in different areas of chemistry, biology and environmental science will be incorporated in teaching.

本项目将研究气相、表面、团簇环境和强激光场存在下的电子-分子碰撞过程。一个特别的重点将是生物相关的分子，如简单的氨基酸，其中基本的电子连接机制将被调查。还将研究激光场在电子-分子相互作用中的作用，这项研究将在碰撞物理学与化学控制、放射生物学和大气科学相联系的领域创造新的知识。这项研究将涉及跨学科的努力和与其他领域的科学家合作。它将在更广泛的领域培训学生，包括几个分支学科。在教学中，将结合一些例子，说明低能电子在化学、生物学和环境科学不同领域中的作用。
