This standard grant will provide partial support for two graduate students to supervise the construction and commissioning of the ICEBall-2 mini-orange spectrometers within the Gammasphere array, a premier detection system used by a large consortium of nuclear-structure physicists. This large gamma-ray detector array is used to study the complex level structure of nuclei in order to understand the underlying nuclear structure. The mini-orange spectrometers allow measurements of internal conversion electrons, which result from electromagnetic transitions between levels for which there is no change in angular momentum, which typically arise from interband transitions. Observing these transitions thus allows a more complete understanding of the level schemes. The research using this device will be performed at the ATLAS facility at Argonne National Laboratory.

这项标准赠款将为两名研究生提供部分支持，以监督Gammaserma阵列内的ICEBall-2小型橙色光谱仪的建造和调试，Gammaserma阵列是一个大型核结构物理学家联盟使用的首要检测系统。 这种大型伽马射线探测器阵列用于研究原子核的复杂能级结构，以了解潜在的核结构。 迷你橙色光谱仪允许测量内部转换电子，这是由水平之间的电磁跃迁引起的，其中角动量没有变化，这通常是由带间跃迁引起的。 因此，观察这些转变可以更完整地理解能级方案。 使用该器械的研究将在阿贡国家实验室的ATLAS机构进行。
