Structure and Shape of Nuclei at High Angular Momentum

这项标准拨款将为两名研究生提供部分支持，以监督伽玛球阵列中ICEBall-2微型橙色光谱仪的建造和调试，伽玛球阵列是一个大型核结构物理学家联盟使用的首要探测系统。这种大型伽玛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。微型橙色光谱仪允许测量内部转换电子，这是由角动量没有变化的能级之间的电磁转换引起的，通常是由带间转换引起的。观察这些转变可以让我们更全面地理解关卡方案。使用该设备的研究将在阿贡国家实验室的ATLAS设备上进行。

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.
