U.S.-France Cooperative Research: Dynamical Interaction of Negative Ions with Metal Surfaces

9314529 Norlander这个为期三年的奖项支持美国-法国在材料理论方面的合作研究，该研究由莱斯大学的Peter A. J. Norlander和奥赛巴黎大学的Jean-Pierre Gauyacq和Dominique Teillet- Billy共同完成。他们的研究目的是增加对原子表面散射中负离子形成动力学的理解。这项研究还将包括对原子极化和金属表面附近的像力等效应的研究。美国研究者为这次合作带来了表面理论方面的专业知识。法国研究人员在原子和分子物理学方面的专业知识也补充了这一点。该项目还利用了两种互补而又截然不同的方法来计算能量转移和原子状态寿命，这两种方法分别由美国和法国的研究小组开发。原子/分子如何与表面相互作用的理论的发展是我们理解催化和腐蚀等过程的基础。这个项目将在总体上推进该理论和表面物理领域。＊＊＊

9314529 Norlander This three-year award supports U.S.-France cooperative research in materials theory between Peter A. J. Norlander at Rice University and Jean-Pierre Gauyacq and Dominique Teillet- Billy at the University of Paris, Orsay. The objective of their research is to increase understanding of the dynamics of negative ion formation in atom-surface scattering. This investigation will also include the study of effects such as the polarization of the atom and the image force near a metal surface. The U.S. investigator brings to this collaboration expertise in surface theory. This is complemented by the French investigators' expertise in atomic and molecular physics. The project also takes advantage of two complementary, yet contrasting methods for calculating energy shifts and the lifetimes of atomic states which were developed respectively by the U.S. and French groups. The development of a theory on how atoms/molecules interact with surfaces is fundamental to our understanding of processes such as catalysis and corrosion. This project will advance that theory and the field of surface physics in general. ***
