CAREER: Ground State Magnetic Moments of Short-lived Nuclei Using Beta-NMR Spectroscopy

将测量质子滴线附近短寿命放射性同位素的磁偶极矩，以探索质子和中子在束缚核中被视为相同粒子的极限。这些实验将在密歇根州立大学的国家超导回旋加速器实验室进行。利用耦合的K500-K1200回旋加速器提供的中能重离子束的碎裂，并使用新的A1900碎片分离器从其他物种中挑选，将产生所需的放射性原子核。核磁共振的方法将被用来推断非常轻的镁和硅同位素的基态磁矩。还将开发一种使用核磁共振和泛音光谱直接测量核基态自旋的方法。国家超导回旋加速器实验室最先进的研究设施为推进本科生、研究生和博士后的核化学教育提供了独特的舞台。大学回旋加速器设施的环境允许为所有级别的学生提供实践培训体验。为了将实用的核科学经验带到课堂上，密歇根州立大学将开发一个新的初级/高级化学课程。本课程将为学生提供基本的核过程和辐射探测技术的背景知识。然后，学生将应用这一新知识来理解尖端核科学研究以及拥有铁斯托核科学的时事。

The magnetic dipole moments of short-lived radioisotopes near the proton drip-line will be measured to explore the limit at which protons and neutrons can be treated as identical particles in the bound nucleus. The experimentswill be performed at the National Superconducting Cyclotron Laboratory atMichigan State University. The desired radioactive nuclei will be producedusing the fragmentation of intermediate-energy heavy-ion beams provided by the Coupled K500-K1200 Cyclotron Facility and selected from other species using the new A1900 fragment separator. The method of nuclear magnetic resonance on beta-emitting nuclei will be employed to deduce the ground state magnetic moments of very light magnesium and silicon isotopes. A method to directly measure the spin of the nuclear ground state will also be developed usingnuclear magnetic resonance and overtone spectroscopy. The state-of-the-art research facilities at the National Superconducting Cyclotron Laboratory provide a unique arena to advance the nuclear chemistry education of undergraduate, graduate, and postdoctoral students. The environment at the university-based cyclotron facility allows for a hands-on training experience for students at all levels. To bring practical nuclearscience experience to the classroon, a new junior/senior level chemistry class will be developed at Michigan State University. This course will provide students with a background in fundamental nuclear process and radiation detectiontechniques. Students will then apply this new knowledge to understand both cutting edge nuclear science research as well as current events having tiesto nuclear science.
