Photonuclear Reactions

本提案是为了支持实验亚原子物理学的一个研究项目。这项研究的目标是，进一步了解构成原子核的粒子（中子和质子）的基本特性，测试我们对这些粒子之间相互作用的知识，并测试我们对基本物理原理的理解。这将通过测量由光子和来自原子核的光子散射引发的轻核上的核反应来完成。光子测量将主要使用来自北卡罗来纳州达勒姆杜克大学自由电子激光设施的高强度伽玛源的线性和圆偏振光子来完成，这是世界上唯一能够允许我们进行这项工作所需的精确测量的设施。这些研究将促进世界在基础物理方面的知识。准备进行测量的设备将推进核与辐射探测技术，并向加拿大人员提供先进技术方面的培训。

This proposal is to support a research program in Experimental Subatomic Physics. The goals of this research are, to further our understanding of the fundamental properties of the particles that make up the atomic nucleus (neutrons and protons), to test our knowledge of the interactions between these particles, and to test our understanding of fundamental physics principles. This will be accomplished by measurements of nuclear reactions on light nuclei that are initiated by photons and by photon scattering from the nucleus. The photon measurements will be accomplished primarily using linearly and circularly polarized photons from the High Intensity Gamma Source at the Duke University Free Electron Laser facility in Durham, North Carolina which is the only facility in the world capable of allowing us to make the precision measurement needed for this work. These studies will advance the world’s knowledge in fundamental physics. Preparing equipment to make the measurements will advance nuclear and radiation detection technology and provide training to Canadian personnel in advance technologies.
