9452430 Croft This project will enrich our junior year modern physics lab by introducing state-of-the-art experimental and data analysis techniques drawn directly from research. The proposers are two nuclear experimentalists and a solid state x-ray spectroscopist who are committed to the goal of infusing this undergraduate lab with a taste of the excitement and the power of modern research methods, while maintaining the role of the lab as a teaching lab. The proposed experiments are drawn from the expertise of the principal investigators. Specifically one of the enrichments involves introducing truly modern particle/nuclear physics techniques into an experiment on the muon lifetime and the directional dependence of cosmic rays. The second involves a two part introduction to modern x-ray spectroscopic methods. Students will first explore nuclear and atomic energy level schemes by fluorescent radiation with a sophisticated high resolution x-ray detection system. The second part involves the introduction to x-ray absorption spectroscopy (XAS) the data analysis and experimental methods. For the actual XAS measurements students will make a data collection trip to the Brookhaven National Synchrotron Light Source which should have a particularly high motivational impact on them.

9452430克罗夫特这个项目将通过引入最先进的实验和直接从研究中提取的数据分析技术来丰富我们三年级的现代物理实验室。提出者是两名原子核实验者和一名固态X射线光谱仪专家，他们致力于为这个本科生实验室注入现代研究方法的刺激和力量，同时保持实验室作为教学实验室的作用。拟议的实验是从主要调查人员的专业知识中得出的。具体地说，其中一项丰富内容涉及将真正的现代粒子/核物理技术引入到关于宇宙射线的介子寿命和方向相关性的实验中。第二部分包括对现代X射线能谱方法的两部分介绍。学生将首先利用先进的高分辨率x射线探测系统，通过荧光辐射来探索核能和原子能级方案。第二部分介绍了X射线吸收光谱(XAS)、数据分析和实验方法。对于实际的XAS测量，学生们将前往布鲁克海文国家同步加速器光源进行数据收集之旅，这将对他们产生特别高的动机影响。
