RUI: Studies of Neutron-Rich Rare Isotopes With the Modular Neutron Array (MoNA) Detector at the National Superconducting Cyclotron Laboratory (NSCL)

Concordia学院将参与在国家超导回旋加速器实验室使用模块化中子阵列（莫纳）进行快速稀有同位素实验的富中子核研究。位于Moorhead的Concordia学院是莫纳联盟的成员，在测试和组装莫纳探测器模块方面发挥了主导作用。Concordia的本科生将使用莫纳探测器参加NSCL的实验，并在Concordia学院对这些实验期间采集的数据进行分析。莫纳计划于2003年春季上线，Concordia学院将参与利用莫纳开始一项沿着中子滴线研究核系统的计划。 莫纳的高探测效率（70%）和模块化设计将允许通过选择的碎裂反应来研究短寿命核的结构。一旦目前正在佛罗里达州立大学建造的清扫磁铁投入使用，莫纳将被用来探索富含中子的核的分裂，同时被清扫磁铁偏转的带电碎片。用序贯粒子衰变谱研究远离稳定核的中子束缚基态。 此外，将探索使用莫纳探测器和扫掠器研究多中子晕和富中子系统中的集体激发.

Concordia College will participate in the investigation of neutron-richnuclei using the Modular Neutron Array (MoNA) in experiments with fast rareisotopes at the National Superconducting Cyclotron Laboratory. Concordia College at Moorheadis a member of the MoNA Consortium and has played a leading role in testingand assembling the MoNA detector modules. Concordia undergraduate studentswill participate in experiments at the NSCL using the MoNA detector and perform analysis at Concordia College on the data taken during these experiments. MoNA is planned to come online in the Spring of 2003.Concordia College will be part of the effort to use MoNA to begin a programof study of nuclear systems along the neutron drip-line. The high detectionefficiency (70%) and modular design of MoNA will allow the study of thestructure of short-lived nuclei via selected break-up reactions. Once thesweeper magnet, currently being constructed at Florida State University,becomes operational MoNA will be used to explore the break-up of veryneutron-rich nuclei in coincidence with the charged fragments being deflected by the sweeper magnet. The neutron-unbound ground states of nuclei far from stability will be studied using sequentialparticle decay spectroscopy. In addition studies of multi-neutron halos and collectiveexcitations in neutron-rich systems using the MoNA detector and the sweeper will beexplored.
