CAREER: Weak Interactions in the Nucleus

将在实验核物理学方面开展研究，并将为研究生一级的核物理教学开发新的工具。 核心研究活动是一系列旨在阐明复杂系统中弱相互作用过程的核结构贡献的实验。 不稳定核的衰变主要由弱相互作用驱动。 拟议的测量是非常精确的性质，并将解决小的影响，限制了我们的弱相互作用的详细了解。 具体而言，将进行测量，以提高对罕见的双β衰变过程、同位旋对称性破缺及其在使用弱探针或强子探针提取弱相互作用强度时引入的复杂性、介子交换电流对弱相互作用强度的可能影响、以及弱相互作用（本质上主要是矢量/伪矢量）的可能的小标量部分。 教育与研究的结合是拟议活动的一个同样重要的方面。 这些实验将在巴黎圣母院串联货车德格拉夫和欧洲的几个粒子加速器上进行。 研究生和本科生将致力于拟议研究的各个方面，以扩大他们的研究培训和发展他们的研究技能。 明确涉及到这个PI的整体学术活动的教学部分，一组新的问题，在核物理将开发这将提供一个更现代的基础上，在研究生水平的核物理教学。

Research will be carried out in experimental nuclear physics and new tools will be developed for teaching nuclear physics at the graduate level. The central research activity is a series of experiments designed to elucidate nuclear structure contributions to weak interaction processes in complex systems. The decays of unstable nuclei are driven principally by the weak interaction. The proposed measurements are very precise in nature and will address small effects which limit our detailed understanding of the weak interaction. Specifically, measurements will be carried out aimed at improving the understanding of the rare double beta decay process, of isospin symmetry breaking and the complexities it introduces in extracting the weak interaction strength using weak probes or hadronic probes, of possible effects of meson exchange currents on weak interaction strengths, and of possible small scalar parts of the weak interaction (which is predominantly vector/pseudo- vector in nature). Integration of education and research is an equally important facet of the proposed activity. The experiments will be carried out at the Notre Dame tandem Van de Graaff, and at several particle accelerators in Europe. Graduate and undergraduate students will work on all aspects of the proposed research to broaden their research training and develop their research skills. Relating explicitly to the teaching part of this PI's overall academic activity, a new set of problems in nuclear physics will be developed which will provide a more contemporary basis for teaching nuclear physics at the graduate level.
