9317429加里森这个项目是在表面科学领域，重点是在高能粒子轰击引起的表面化学反应的坚定的理论认识的发展。 在这项为期三年的资助计划下，Garrison教授和她的学生将模拟keV粒子轰击吸附在金属表面上具有催化作用的小有机分子，表面诱导解离过程中，30-200 eV的有机分子撞击表面，最后是keV粒子轰击薄膜，包括自组装单层和聚合物。 重点将是检查在这些事件中发生的反应，然后将基本过程与实验观察相关联。 这项研究带来了现代表面理论和计算化学，以了解粒子轰击如何在表面引起化学反应。 在这项工作的过程中得到的模型将是重要的复杂材料的研究进展，如催化剂，有机薄膜和生物细胞。 ***

9317429 Garrison This project is in the area of surface science and focusses on the development of a firm theoretical understanding of chemical reactions at surfaces induced by energetic particle bombardment. During the tenure of this three-year continuing grant, Professor Garrison and her students will model keV particle bombardment of small organic molecules adsorbed on metal surfaces which are of catalytic interest, surface induced dissociation processes in which a 30-200 eV organic molecule strikes a surface, and finally the keV particle bombardment of thin films including self assembled monolayers and polymers. The emphasis will be on examining reactions that occur during each of these events and then relating the fundamental processes to experimental observations. %%% This research brings modern surface theory and computational chemistry to bear on understanding of how particle bombardment causes chemical reactions at surfaces. Models derived in the course of this work will be important to progress in the study of complex materials as diverse as catalysts, organic thin films, and biological cells. ***
