U.S.-Brazil Cooperative Project in Atomic Collisions with Pontifical Catholic University of Rio de Janeiro

这项来自美国-巴西合作科学项目的奖金将支持斯坦福大学的Walter E. Meyerhof博士和巴西巴西里约热内卢教皇天主教大学的Eduardo C. Montenegro博士在物理学方面的合作研究。该项目侧重于离子弹丸撞击气体目标时电荷变化过程（电子捕获和损失）的研究。这种持续和成功的合作将在斯坦福大学FN串联加速器和宗座天主教大学的范德格拉夫加速器上进行。本文将重点研究各种光弹穿过氢气和氦气靶时电子损失中的电子-电子相互作用。总损失截面和微分损失截面都将被测量。一个原子氢靶将在巴西建立，这将使研究分子氢和原子氢与轻射体相互作用之间的差异成为可能。

This award from the U.S.-Brazil Cooperative Science Program will support collaborative research in Physics to be carried out by Dr. Walter E. Meyerhof of Stanford University and Dr. Eduardo C. Montenegro of Pontifical Catholic University of Rio de Janeiro, Brazil. The project focuses on the study of charge changing processes (electron capture and loss) by ionic projectiles impinging on gaseous targets. This continuing and successful collaboration will be carried out at the Stanford University FN Tandem accelerator and at the Van de Graaff accelerator at the Pontifical Catholic University. The study will focus on the electron-electron interaction in the electron loss by various light projectiles passing through hydrogen and helium gas targets. Both total and differential loss cross sections will be measured. An atomic hydrogen target will be constructed in the Brazilian site that will enable investigation into the differences between molecular and atomic hydrogen interacting with light projectiles.
