Studies of Chemical Processes Using Rydberg Atoms

邓宁得到了实验物理化学计划的支持，继续研究由高里德伯原子引起的化学过程。将对各种负离子的形成和性质进行全面的研究，重点是(1)热和亚热电子能下解离电子捕获的动力学，(2)自分离物种的寿命及其通过与第二体相互作用的能量转移的稳定性，(3)偶极结合负离子的物理和化学性质，以及(4)寻找四极结合负离子。本研究的结果有望增强对供体和受体系统之间电子交换的基本理解。大量的化学反应涉及分子间电子的转移。里德伯原子碰撞方法为提高对导致负离子的电子交换过程的理解提供了新的机会。负离子及其性质影响着各种实际应用，包括材料的等离子体处理和高压电气设备的不导电介质的发展。

Dunning is supported by the Experimental Physical Chemistry Program to continue his studies of chemical processes induced by high Rydberg atoms. A comprehensive study of the formation and properties of a variety of negative ion species will be performed, with emphasis on (1) the dynamics of dissociative electron capture at thermal and sub-thermal electron energies, (2) the lifetimes of autodetaching species and their stabilization by energy transfer via interactions with a second body, (3) the physical and chemical properties of dipole-bound negative ions, and (4) the search for quadrupole-bound negative ions. Outcomes from this research are expected to enhance the fundamental understanding of electron exchange between donor and acceptor systems.A large number of chemical reactions involve the transfer of electrons between molecules. Rydberg atom collision methods provide new opportunities for improving the understanding of electron exchange processes leading to negative ions. Negative ions and their properties impact various practical applications, including plasma processing of materials and the development of nonconducting media for high-voltage electrical equipment.
