Photonuclear Reactions

这项提议是为了支持一项实验亚原子物理的研究计划。这项研究的目标是，进一步了解组成原子核的粒子(中子和质子)的基本性质，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。这将通过测量轻原子核上由光子引发的核反应和通过原子核的光子散射来实现。光子测量将主要使用位于北卡罗来纳州达勒姆的杜克大学自由电子激光设施的高强度伽马源的线偏振和圆偏振光子来完成，该设施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对基础物理学的了解。准备进行测量的设备将推进核和辐射探测技术，并为加拿大人员提供先进技术培训。

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.
