This project aims to address a persistent question in our understanding of atomic nuclei. The nature of low-lying excitations, K=0+ bands in deformed nuclei remain enigmatic in the field. The effort focuses on the search for vibrational excitations in the Gadolinium isotopes. Measurements will be conducted at the University of Kentucky Accelerator Facility (UKY), and analysis will be performed at the Institute for Structure & Nuclear Astrophysics (ISNAP) at the University of Notre Dame (ND) during the three summers of the duration of the grant period and at the University of Wisconsin - La Crosse (UW-L) during the academic year. The UW-L group will set-up, run, and analyze a series of (n,n'gamma) experiments during this time. To prepare the students for this summer work, the UW-L Nuclear Science Group will concentrate on detector work and analysis during the academic year. The results will be broadly disseminated through publications and conference presentations by the PI and undergraduate researchers. The primary broader impact of this project is to promote teaching and learning, while extending scientific innovation and understanding. All aspects of this project will be completed in a collaborative environment with UW-L undergraduates. The project will support an undergraduate research program that has a mentoring plan based on teaching rigorous analytical principles and on engaging undergraduates in research as freshmen or sophomores. Early engagement provides students with adequate time to develop advanced skills and participate in multiple stages of research, from experimental design to dissemination at conferences and in publications. The UW-L Nuclear Group strives to quickly develop a sense of independence in the undergraduate researcher. The goal is to continue to do relevant, potentially transformative science that is valued by the scientific community as a whole and simultaneously to transform the students from passive classroom learners to active researchers as they take responsibility for their particular research. This is accomplished by having regular group meetings and frequent individual planning meetings but then allowing the students to work independently with modern instrumentation. As a result, they learn planning, running experiments, analysis, modeling, and communication skills. Experience shows that undergraduate research enhances a student's education and better prepares the student for graduate work or for a wide variety of science careers in either industry or academia.

这个项目旨在解决我们对原子核理解中的一个长期存在的问题。形变核中低激发态K=0+带的本质仍然是场中的谜团。这项工作的重点是寻找Gd同位素中的振动激发。测量将在肯塔基大学加速器设施(UKY)进行，分析将在圣母大学(ND)结构与核天体物理研究所(ISNAP)和威斯康星大学拉克罗斯大学(UW-L)在赠款期间的三个夏天进行。威斯康星大学L小组将在此期间建立、运行和分析一系列(n，n‘Gamma)实验。为了让学生为这次暑期工作做好准备，威斯康星大学L核科学小组将在本学年专注于探测器工作和分析。结果将通过出版物和国际和平研究所和本科生研究人员的会议报告广泛传播。该项目的主要更广泛影响是促进教和学，同时扩大科学创新和理解。这个项目的所有方面都将在与威斯康星大学L本科生合作的环境中完成。该项目将支持一个本科生研究项目，该项目有一个指导计划，该计划的基础是教授严格的分析原理，并让本科生在大一或大二时参与研究。早期参与为学生提供了足够的时间来发展高级技能并参与研究的多个阶段，从实验设计到在会议和出版物上的传播。UW-L核集团努力在本科研究员中迅速培养独立意识。其目标是继续从事相关的、潜在的变革性科学，这些科学受到整个科学界的重视，同时将学生从被动的课堂学习者转变为积极的研究人员，因为他们对自己的特定研究负责。这是通过定期举行小组会议和频繁的个人计划会议来实现的，但随后允许学生使用现代仪器独立工作。因此，他们学习规划、运行实验、分析、建模和沟通技能。经验表明，本科生的研究提高了学生的教育，更好地为学生的研究生工作或在工业或学术界的各种科学职业做好准备。
