U.S.-Brazil Cooperative Research on Studies of Electron- Molecule Collisions and Molecular Photoionization

该奖项支持加州理工学院的文森特·麦科伊与三位巴西同事在分子-电子碰撞和光电离方面的合作研究，这三位同事是：坎皮纳斯大学的M.A.P.利马和L.M.布雷桑辛，以及巴西圣卡洛斯联邦大学的L.E.马查多。研究人员打算研究低能电子与分子的碰撞以及非线性多原子分子的光致电离。这项工作是基于专门为电子-分子碰撞建立的Schwinger变分原理，以及对于分子光电离，基于使用可分势的Lippmann-Schwinger方程的数值解。加州理工大学麦考伊教授的团队是电子碰撞分子激发领域的主要团队之一。他们的出版物质量最高，他在国际上享有广泛的声誉。近年来，这些巴西科学家都在加州理工学院与该团队合作，并与研究生和其他科学家一起在巴西建立了研究小组。拟议的工作将继续它们卓有成效的国际合作。

This award supports cooperative research in molecular-electron collisions and photoionization between Vincent McKoy at Caltech and three Brazilian colleagues: M.A.P. Lima and L.M. Brescansin of the Universidad Estadual de Campinas, and L.E. Machado, of the Universidade Federal de Sao Carlos in Brazil. The researchers intend to study the collisions of low-energy electrons with molecules and the photoionization of nonlinear polyatomic molecules. This work is based on a Schwinger variational principle specifically formulated for electron-molecule collisions and, for molecular photoionization, on a numerical solution of the Lippmann-Schwinger equation using separable potentials. Professor McKoy's group at Caltech is one of the leading groups in the area of electron impact molecular excitations. Their publications have been of highest quality and he has a wide international reputation. The Brazilian scientists have all worked with the group at Caltech in recent years and have established research groups in Brazil with graduate students and other scientists. The proposed work will continue their fruitful international collaboration.
