A Program of Intermediate Energy Nuclear Physics

9420787内森将在高能电子散射、光子核反应和μ子的基本性质方面进行研究，目的是确定核子的自旋和香味结构，观察原子核中夸克自由度的表现，以及探测μ子的强子结构（在确定μ子的异常磁矩方面改进了20倍）。这些领域的研究将促进我们对组成夸克和海夸克（围绕组成夸克的夸克-反夸克对）方面的核子的理解，并探测TeV质量尺度强子以及它们如何通过辐射修正影响电弱过程。这些主题是核物理和粒子物理中最令人兴奋的。主要先进设备的开发和建设，包括激光泵浦极化气体靶、专用探测器和光谱仪，是这项活动不可或缺的一部分。研究生和博士后的教育是伊利诺伊州核物理小组伞式资助的一个重要组成部分。＊＊＊

9420787 Nathan Research will be carried out in high energy electron scattering, photonuclear reactions, and in fundamental properties of the muon with the goals of determining the spin and flavor structure of nucleons, observing manifestations of quark degrees of freedom in nuclei, and in probing the hadronic structure of the muon (a twenty-fold improvement on the determination of the muon's anomalous magnetic moment). Research in these areas will advance our understanding of the nucleon in terms of constituent quarks and sea-quarks (quark-antiquark pairs surrounding the constituent quarks) and probe TeV mass scale hadrons and how they affect electro-weak processes through radiative corrections. These topics are among the most exciting in nuclear and particle physics. Development and construction of major state-of-the-art equipment, including laser-pumped polarized gas targets, specialized detectors, and spectrometers, is integral to this activity. Education of graduate students and postdocs is a strong component in every aspect of this umbrella grant for the Illinois Nuclear Physics group. ***
