U.S.-Mexico Cooperative Research Program: Materials Analysis using the (3He,p) Nuclear Reaction

9314133麦金太尔美国-墨西哥奖将支持亚利桑那大学劳伦斯·麦金太尔教授和墨西哥国立自治大学物理研究所爱德华多·安德拉德·伊巴拉教授的合作。合作者将研究（3HE,p）核反应作为材料分析的工具。在离子束分析（IBA）领域中，有几种主要的分析技术用于检测和定量薄膜和块状材料表层的基本成分和深度分布。主要和最普遍的技术涉及核散射和核反应；然而，这种技术显示出在薄膜或衬底材料中存在高质量元素时对低质量元素缺乏灵敏度。通过使用（3He,p）核反应，本研究将寻找额外的、合适的技术来克服这个问题。实验工作将在实验室之间进行分配，期望在项目结束时，两个实验室都将拥有一种新的强大的材料分析技术。＊＊＊

9314133 McIntyre This U.S.-Mexico award will support a collaboration between Professor Laurence McIntyre of the University of Arizona and Professor Eduardo Andrade Ibarra of the Institute of Physics of the National Autonomous University of Mexico (UNAM). The collaborators will study the (3HE,p) nuclear reaction as a tool for materials analysis. There are several major analytical techniques used in the field of Ion Beam Analysis (IBA) for detecting and quantifying elementary composition and depth distribution in thin films and surface layers of bulk materials. The predominant and most general technique involves nuclear scattering and reactions; however, this technique shows a lack of sensitivity to low mass elements in the presence of higher mass elements in the film or substrate material. Through the use of the (3He,p) nuclear reaction, the present study will search for additional, suitable techniques to overcome this problem. The experimental work will be divided between the laboratories with the expectation that at the end of the project, both labs will possess a new and powerful technique for materials analysis. ***
