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

9314529诺兰德：这个为期三年的奖项支持莱斯大学的彼得·A·J·诺兰德与巴黎大学奥赛分校的让-皮埃尔·高雅克和多米尼克·特伊莱特-比利在材料理论方面的美法合作研究。他们研究的目的是增加对原子-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影响的研究。这位美国研究人员将表面理论方面的专业知识带到了这次合作中。法国研究人员在原子和分子物理方面的专业知识补充了这一点。该项目还利用了两种互补但截然不同的方法来计算能量移动和原子态的寿命，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。该项目将推动这一理论和整个表面物理领域的发展。***

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. ***
