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

0128851 McKoy这个美洲计划奖将支持加州理工学院的Vincent McKoy博士与Marco A.利马和Marcio H.巴西巴拉那联邦大学的贝特加。 该项目的目的是确定为什么使用多种方法从高级计算中获得的微分弹性截面在碰撞能量和散射角的一定范围内表现出与最近的实验惊人的大偏差。 这些计算将产生非常有价值的数据，大大增加了对少数技术和基本重要分子的电子散射的了解。 该项目还促进教育和培训，为巴西物理科学研究生提供机会，获得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.
