In this award, funded by the Experimental Physical Chemistry Program of the Division of Chemistry, Professor Stephen R. Leone of the University of California - Berkeley, together with his postdoctoral and graduate student researchers, will study the dynamics of electrons in atoms, molecules -- from small, xenon difluoride, to large, buckminsterfullerene -- and gold nanoclusters with the new methods of attosecond laser spectroscopy. The goal of this research is to be able to observe the dynamics of the electrons in these species. Electrons are the glue which bind atoms together in chemical bonds and are the principal species in matter that interact with light. A better understanding of the dynamics of these electrons in these species will shed light on electronic processes in matter. The timescale for the dynamics of electrons in atoms, molecules and clusters is on the sub-femtosecond timescale -- a timescale that has been impossible to probe directly until quite recently. Electron dynamics are at the heart of a number of photophysical and photochemical processes. Prof. Leone will continue to mentor undergraduate, graduate and postdoctoral researchers in his laboratory -- a large number of which have gone on to jobs in academia and industry. In addition, Prof. Leone plans to continue his outreach with Lowell High School -- a San Francisco City school.

在这个由化学系实验物理化学项目资助的奖项中，斯蒂芬·R·加州大学伯克利分校的Leone和他的博士后及研究生研究人员将利用阿秒激光光谱学的新方法，研究原子、分子（从小的二氟化氙到大的巴克敏斯特富勒烯）和金纳米团簇中电子的动力学。 这项研究的目标是能够观察这些物种中电子的动力学。电子是将原子以化学键结合在一起的粘合剂，是物质中与光相互作用的主要物质。 更好地理解这些物种中这些电子的动力学将有助于了解物质中的电子过程。 原子、分子和团簇中电子动力学的时间尺度是亚飞秒时间尺度--直到最近才能直接探测到的时间尺度。 电子动力学是许多光物理和光化学过程的核心。 Leone教授将继续指导他实验室的本科生、研究生和博士后研究人员，其中许多人已经在学术界和工业界工作。 此外，莱昂教授计划继续与洛厄尔高中--一所位于旧金山弗朗西斯科市的学校--进行外联。
