Nuclear Structure of Exotic Nuclei

这个研究计划的主要目标是提供发展平均场理论所需的证据，该平均场理论将在从稳定到稳定极限的整个核景观中具有强大的预测能力。这项研究将利用一流的新放射束设施，即Argonne的ATLAS-Cariu、密歇根州立大学的ReA3/NSCL、日内瓦的TRIUMF/ISAC2和CERN/Isolde，以探索远离稳定的未探测核区域中的异常核结构现象。电磁激发(库仑激发)和核子转移反应将是研究的重点。该计划将开启新的研究机会，并为充分利用密歇根州立大学正在建设的FRIB设施奠定基础。该小组将继续为核科学做出重要的技术贡献。以前的例子，如重离子探测器CHICO和BAMBINO，以及对伽马射线探测器阵列Gammasphere、Gretina/Greta的贡献，以及库仑激发、重离子诱导转移和裂变碎片能谱技术，都是罗切斯特多年来努力的成果。将开发新一代重离子探测器CHICO2，以实现与下一代高分辨率伽马射线跟踪探测器系统Gretina/Greta和TIGRESS的最终分辨率。这样的探测器系统将提供比目前可用的分辨率高出几个数量级的分辨率，使目前核科学无法获得的研究成为可能。除了对核科学产生巨大影响外，这种伽马射线跟踪和成像探测器的潜在影响在科学、医学、工业和核保障方面也有广泛的应用。拟议的研究和探测器开发计划是研究生和博士后教育的理想环境。

The primary goal of this research program is to provide the evidence needed to develop a mean field theory that will have strong predictive power throughout the nuclear landscape from stable to the limits of stability. The research will exploit the premier new radioactive beam facilities, namely ATLAS-CARIBU at Argonne, ReA3/NSCL at Michigan State University, TRIUMF/ISAC2 and CERN/ISOLDE in Geneva in order to probe unusual nuclear structure phenomena in unexplored regions of nuclei far from stability. Electromagnetic excitation (Coulomb excitation) and nucleon transfer reactions will be the experimental probes emphasized in the research. The program will open new research opportunities as well as provide a foundation enabling full exploitation of the FRIB facility now under construction at Michigan State University. The group will continue making important technical contributions to nuclear science. Prior examples such as heavy-ion detectors CHICO and Bambino, as well as contributions to the gamma-ray detector arrays Gammasphere, GRETINA/GRETA, and the techniques of Coulomb excitation, heavy-ion induced transfer, and fission-fragment spectroscopy, are the culmination of many years of effort at Rochester. A new generation heavy-ion detector, CHICO2 will be developed in order to achieve the ultimate resolution with the next generation high-resolution gamma-ray tracking detector systems GRETINA/GRETA and TIGRESS. Such detector systems will provide a resolving power that is orders of magnitude better than currently available, enabling studies that at present are inaccessible to nuclear science. Besides having an enormous impact on nuclear science, the potential impact of such gamma-ray tracking and imaging detectors has a wide range of applications to science, medicine, industry, and nuclear safeguards. The proposed research and detector development programs are an ideal environment for graduate and post-doctoral education.
