The Hope College Nuclear Group will continue its study of neutron-rich unstable nuclei near the drip-line with the Modular Neutron Array (MoNA) at the National Superconducting Cyclotron Laboratory (NSCL) and will continue to apply a variety of nuclear techniques (e.g. Particle Induced X-Ray Emission, Rutherford BackScattering, Nuclear Reaction Analysis, and Ion Beam Induced Luminescence) to a range of interdisciplinary questions with the Hope Ion Beam Analysis Laboratory. This proposal will support two faculty in these efforts, each of which will include undergraduate researchers in all aspects of the research.The Nuclear Group will investigate unstable neutron-rich nuclei to refine the theoretical understanding of the nuclear shell model. This will involve measurements of excited states and ground states of unstable nuclei created at the NSCL and measured with the MoNA-LISA/Sweeper system. The Nuclear Group, as part of the overall program, will supervise the construction of Large-area multi-Institutional Scintillator Array (LISA) by 12 undergraduate institutions in the MoNA Collaboration (MRI:PHY-0922794). The interdisciplinary portion of the proposed research will examine metalloprotein stoichiometry (deposited on mylar foils), forensic characterization of layered automotive paints and automotive glass fragments, and luminescence studies of feldspars and carbonates. On-going analysis of previous experiments and development projects will continue. Interdisciplinary collaborative efforts will also continue with other Hope researchers (electropolymer characterization, superconductor and electrodeposited thin film stoichiometry) and groups outside Hope College (metal contamination in sediments, provenance of river sediment, detector characterization, and aerosol measurements). All of these initiatives are not only important for the specific science result they yield, but for possible far-reaching impact on the analytical techniques used in many areas.

希望学院核小组将继续利用国家超导回旋加速器实验室的模块化中子阵列研究滴线附近的富中子不稳定核，并将继续应用各种核技术（例如，粒子感应X射线发射、卢瑟福背散射、核反应分析，和离子束诱导发光），以一系列跨学科的问题与希望离子束分析实验室。该提案将支持两个学院开展这些工作，每个学院都将包括研究各个方面的本科研究人员。核小组将研究不稳定的富中子核，以完善对核壳模型的理论理解。这将涉及在NSCL创建的不稳定核的激发态和基态的测量，并使用MoNA-LISA/Sweeper系统进行测量。作为整体计划的一部分，核小组将监督莫纳协作（MRI：PHY-0922794）中12个本科院校的大面积多机构闪烁体阵列（丽莎）的建设。拟议研究的跨学科部分将检查金属蛋白化学计量（沉积在聚酯薄膜上），分层汽车油漆和汽车玻璃碎片的法医表征，以及发光研究的晶石和碳酸盐。将继续对以前的实验和开发项目进行分析。 跨学科的合作努力也将继续与其他希望研究人员（电聚合物表征，超导体和电沉积薄膜化学计量）和希望学院以外的团体（沉积物中的金属污染，河流沉积物的来源，检测器表征和气溶胶测量）。 所有这些举措不仅对它们产生的具体科学成果很重要，而且对许多领域使用的分析技术可能产生深远的影响。
