Catalyst Projects provide support for Historically Black Colleges and Universities (HBCU) to work towards establishing research capacity of faculty to strengthen science, technology, engineering and mathematics undergraduate education and research. It is expected that the award will further the faculty member's research capability, improve research and teaching at the institution and involve undergraduate students in research experiences. The project at Virginia State University seeks to establish a nuclear science research group that will investigate neutron-unbound states of oxygen isotopes at the Facility for Rare Isotope Beams (FRIB) at Michigan State University.This proposed work focuses on two areas: (1) analysis of data from past measurements performed with the MoNA (the Modular Neutron Array) Collaboration at National Superconducting Cyclotron Laboratory (NSCL) and (2) the development of a new segmented target to probe the structure of neutron rich nuclei. The former (1) will examine past measurements of various decay channels in order to extract information about the 27O level structure. It will involve computer programming to analyze and visualize the data as well as perform simulations using the GEANT4 toolkit to interpret the results. This data set was recorded during the first experiment to utilize a new segmented target designed to increase statistics for Radioactive Isotope Beam (RIB) experiments to study neutron-unbound systems using the invariant mass spectroscopy technique. The latter (2) will help inform the design, testing and construction of an upgraded target system, the Multilayered Active target for MoNA Experiments (MAME), that will use a gas electron multiplier (GEM) based detector to track the outgoing reaction and decay fragments. A GEANT4 simulation will be developed as part of the design process and for use in the data analysis of future experiments that will use MAME. The resulting device will provide a new tool for measuring neutron-unbound systems thus contributing to the ongoing investigation of the rich structure of atomic nuclei.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

催化剂项目为历史上的黑人学院（HBCU）提供了支持，以努力建立教师的研究能力，以增强科学，技术，工程和数学的本科教育和研究。可以预期，该奖项将进一步进一步促进教职员工的研究能力，改善机构的研究和教学，并让本科生参与研究经验。 The project at Virginia State University seeks to establish a nuclear science research group that will investigate neutron-unbound states of oxygen isotopes at the Facility for Rare Isotope Beams (FRIB) at Michigan State University.This proposed work focuses on two areas: (1) analysis of data from past measurements performed with the MoNA (the Modular Neutron Array) Collaboration at National Superconducting Cyclotron Laboratory (NSCL) and (2) the开发一个新的分段靶标，以探测中子富核的结构。前者（1）将检查各种衰减通道的过去测量值，以提取有关27O级结构的信息。它将涉及计算机编程以分析和可视化数据，并使用Geant4工具包进行模拟来解释结果。在第一个实验中记录了该数据集，以利用一个新的分段靶标，旨在增加放射性同位素束（RIB）实验的统计数据，以使用不变的质谱技术来研究中子毫无疑问系统。后者（2）将有助于告知升级目标系统的设计，测试和构建，这是MONA实验的多层主动目标（MAME），该目标将使用基于气体电子乘数（GEM）检测器来跟踪外向反应和衰减片段。将开发Geant4仿真作为设计过程的一部分，并用于用于使用MAME的未来实验的数据分析。最终的设备将提供一种新工具来测量中子毫无疑问的系统，从而有助于对原子核的丰富结构进行持续的研究。该奖项反映了NSF的法定任务，并被认为值得通过基金会的知识分子优点和更广泛的影响标准通过评估来进行评估。
