U.S.-Brazil Cooperative Research: Near-Threshold Electron-Molecule Collision Dynamics

0128851 McKoy这一美洲计划奖项将与巴西坎皮纳斯大学的Marco A.Lima博士和巴西巴拉那联邦大学的Marcio H.Bettega博士合作，支持加州理工学院的文森特·McKoy博士。该项目的目的是确定为什么在碰撞能量和散射角的特定范围内，使用多种方法从高层计算获得的弹性微分截面与最近的实验出现了惊人的巨大偏差。这些计算将产生非常有价值的数据，大大增加对少数技术上和根本上重要的分子的电子散射的了解。该项目还促进了教育和培训，为巴西自然科学研究生提供了将大规模并行计算应用于科学问题的经验。

0128851McKoyThis Americas Program award will support Dr. Vincent McKoy of the California Institute of Technology in collaboration with Dr. Marco A. Lima of the Universidade Estadual de Campinas, Brazil and Dr. Marcio H. Bettega of the Universidade Federal do Parana, Brazil. The aim of the project is to determine why the differential elastic cross sections obtained from high-level calculations using a number of methods exhibit, within certain ranges of collision energy and scattering angle, surprisingly large deviations from recent experiments. The calculations will produce very valuable data, adding significantly to the knowledge of electron scattering from a handful of technologically and fundamentally important molecules. The project also promotes education and training by providing an opportunity for Brazilian graduate students in the physical sciences to gain experience with the application of large-scale parallel computation to scientific problems.
