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. ***

9420787内森研究将在高能电子散射，光核反应和μ子的基本性质方面进行，目标是确定核子的自旋和味结构，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（μ子反常磁矩测定的20倍改进）。 在这些领域的研究将推进我们的理解核子的组成夸克和海夸克（夸克反夸克对周围的组成夸克）和探测TeV质量尺度强子，以及它们如何影响电弱过程通过辐射校正。 这些主题是核物理和粒子物理中最令人兴奋的。 开发和建造最先进的主要设备，包括激光泵浦偏振气体靶、专用探测器和光谱仪，是这项活动的组成部分。 研究生和博士后的教育是伊利诺伊州核物理小组这项伞式资助的各个方面的重要组成部分。 ***
