Nuclei are the basic building blocks of matter. The entire Universe is composed of nuclei and understanding their properties allows us a glimpse into how the Universe transformed itself to support life. One way to study the properties of nuclei is by exciting and de-exciting the nuclear system. This research focuses on analyzing the lifetimes of the quantum states in deformed nuclei. This project will also contribute to training the next generation of scientists by actively engaging undergraduate students in research at the University of Wisconsin - La Crosse (UW-L).The nature of low-lying excitations, K = 0+ bands in deformed nuclei remain enigmatic in the eld. This project focuses on the search for vibrational excitations in deformed nuclei. The UW-L Nuclear Science Group has recently measured the lifetimes of states in 162Dy during the period of the grant, the group will analyze the results and interpret the implications the measurements. The UW-L Nuclear Science Group will also conduct detector work during the academic year in a small local laboratory. The results will be broadly disseminated through publications and conference presentations by the PI and undergraduate researchers.

原子核是物质的基本组成部分。整个宇宙由原子核组成，了解它们的属性使我们能够一睹宇宙如何转变自身以支持生命。研究原子核特性的一种方法是激发和去激发核系统。这项研究的重点是分析变形核中量子态的寿命。该项目还将通过积极让本科生参与威斯康星大学拉克罗斯分校 (UW-L) 的研究，为培养下一代科学家做出贡献。低位激发的性质，变形核中的 K = 0+ 能带仍然存在在该领域是神秘的。该项目的重点是寻找变形核中的振动激发。威斯康星大学-路易斯安那分校核科学小组最近测量了资助期间 162Dy 的状态寿命，该小组将分析结果并解释测量结果的含义。威斯康星大学-路易斯安那分校核科学小组还将在学年期间在当地的一个小型实验室进行探测器工作。研究结果将通过 PI 和本科生研究人员的出版物和会议演讲来广泛传播。
