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。整个宇宙都是由原子核组成的，了解它们的性质可以让我们一窥宇宙是如何转变自己以支持生命的。研究原子核性质的一种方法是对原子核系统进行激发和去激发。本研究的重点是分析变形原子核中量子态的寿命。该项目还将通过积极吸引威斯康星州-拉克罗斯大学（UW-L）的本科生参与研究来培养下一代科学家。这个项目的重点是在变形核中寻找振动激发。UW-L核科学小组最近测量了162 Dy在资助期间的状态寿命，该小组将分析结果并解释测量的含义。UW-L核科学小组还将在一个小型当地实验室进行学年期间的探测器工作。研究结果将通过PI和本科生研究人员的出版物和会议报告广泛传播。
