RUI: Collaboration to Enhance Participation of Minority and Undergraduate Students in Nuclear Science

该奖项支持一个合作的核物理研究计划，该计划将促进我们对具有高中子质子比的核素的了解，这种核素很有趣，因为它们表现出在稳定核素中没有观察到的行为。实验将在国家超导回旋实验室(NSCL)进行，并在建造完成后为即将到来的稀有同位素束设施做好“第一天”的准备。这些实验包括：研究重核在碎裂前处于激发态的情况，探索和表征铍核的特殊状态，测量镁激发态的分离能，以及研究和开发一种新的粒子探测器。本科生和研究生将与几个美国机构的教职员工合作，进一步推进这项工作，并学习宝贵的高技术技能。这些项目将通过同行评审进行评估，并通过在国家会议、博士论文和期刊文章上的陈述进行传播。该奖项的PI是蒙娜丽莎合作项目的成员，他们计划的实验将利用NSCL通过合作开发的设备的能力(模块化中子阵列和大面积闪烁阵列)。富含中子的核素寿命很短，会通过瞬间的中子发射而衰变，这使得蒙娜丽莎系统成为研究这些原子核的理想工具。项目包括分析数据，实施新技术以更好地识别和解决同质核态，测量丰含中子的核中的非束缚态，表征相对论束流与靶相互作用后的预碎裂动力学，以及研究和开发一种新的基于气体电子倍增器的分段靶。未来的实验将重点放在更高的Z核素上，这些核素在目前的实验装置下是可能的。学生将学习在研究的所有方面使用的宝贵技能，包括探测器建造、数据收集和分析以及传播。

This award supports a collaborative nuclear physics research program that will further our knowledge of nuclides with high ratios of neutrons to protons, which are interesting because they exhibit behavior not observed in stable nuclides. Experiments will be carried out at the National Superconducting Cyclotron Laboratory (NSCL) and be "day-one" ready for the upcoming Facility for Rare Isotope Beams when construction is complete. The experiments include: investigating heavy nuclei in excited states shortly before they fragment, exploring and characterizing particular states of beryllium nuclei, measuring separation energies of excited states of magnesium, as well as research and development of a new particle detector. Undergraduate and graduate students will collaborate with faculty at several US institutions to further this work and learn valuable highly technical skills. The projects will be evaluated through peer review and disseminated through presentations at national conferences, Ph.D. theses, and journal articles.The PIs of this award are members of the MoNA-LISA collaboration, and the experiments they have planned will exploit the capabilities of the equipment that was developed at NSCL by the collaboration (a modular neutron array and a large area scintillation array). Neutron-rich nuclides are very short-lived and decay by prompt neutron emission, making the MoNA-LISA system the ideal tool to investigate these nuclei. Projects include analyzing data, implementing novel techniques to identify better and resolve isomeric nuclear states, measuring neutron-unbound states in neutron-rich nuclei, characterizing pre-fragmentation dynamics after relativistic beams interact with targets, as well as research and development toward a new gas electron multiplier based segmented target. Future experiments focus on higher Z nuclides that are possible with the current experimental setup. The students will learn valuable skills utilized in all facets of research including detector construction, data collection and analysis, and dissemination.
