Nuclear Structure Studies with 4 Detector Arrays

这项为期三年的资助将支持一名教师，一名高级研究员和三名研究生的研究，以调查使用重离子束的库仑激发反应激发的重核结构。 这项研究利用了目前位于劳伦斯伯克利国家实验室的大型伽马射线探测器阵列，Gammasion。 在此期间，该设施将被转移到ATLAS设施在阿贡国家实验室，以利用其他光束可用。 罗切斯特小组利用国家科学基金会的资金，建造了一个4 π带电粒子探测器（紧凑型重离子计数器），它可以与伽马射线管一起使用，大大提高了它在这些测量中的效用。 MPS多学科活动办公室（OMA）将提供部分支持，作为仪器开发的一项扶持性举措的一部分，以提供CHICO所需的修改，以便在ATLAS中使用它，并提供数据分析所需的计算机硬件。 罗切斯特小组将继续使用他们过去研究中已经开发的方法来利用这些新的机会。

This three-year grant will support research by a faculty member, a Senior Research Associate and three graduate students to investigate the structure of heavy nuclei excited by Coulomb excitation reactions using heavy ion beams. The research makes use of the large gamma ray detector array, Gammasphere, which is presently located at Lawrence Berkeley National Laboratory. During the period of this grant this facility will be moved to the ATLAS facility at Argonne National Laboratory to take advantage of other beams available there. Using NSF funds, the Rochester group has constructed a 4-pi charged particle detector (Compact Heavy Ion Counter) which can be used together with Gammasphere to considerably enhance its utility for these measurements. Partial support will be provided by the MPS Office of Multidisciplinary Activities (OMA), as part of an enabling initiative in instrumentation development, to provide for the modifications needed to CHICO in order to use it at ATLAS and for needed computer hardware for data analysis. The Rochester group will continue using the methods already developed in their past research to exploit these new opportunities.
