Nuclear Physics and Its Applications to Astrophysics

9420470麦基翁研究将在高能电子散射中进行，包括确定核子的自旋和味结构，观察夸克自由度在原子核准弹性散射中的表现，以及检验核反应中的颜色透明假说。还将用高能光子和高能质子进行额外的实验，以研究夸克自由度的开始和表现，以及核子中上下反夸克的分布。低能量研究将用光束离子束进行，以研究对理解氦的恒星燃烧、大爆炸核合成和所谓的太阳中微子亏损问题具有重要意义的反应。为了支持这些实验，还将在其他前沿领域开展理论研究，包括：蒙特卡罗壳层模型计算、聚变反应、介子干涉测量以及相干态和压缩态的介子发射。对研究生和博士后的教育是加州理工学院凯洛格实验室运营总括拨款的每一个方面的重要组成部分。***

9420470 McKeown Research will be carried out in high energy electron scattering with the foals of determining the spin and flavor structure of nucleons, observing manifestations of quark degrees of freedom in quasielastic scattering from nuclei, and testing the hypothesis of color transparency in nuclear reactions. Additional experiments will be carried out with high energy photons and high energy protons to study the onset and manifestation of quark degree of freedom, and the up- down-antiquark distribution in the nucleon. Low energy studies will be carried out with beams of light ion to study reactions of importance in understanding stellar burning of helium, big-bang nucleosynthesis, and the so- called solar neutrino deficit problem. Theoretical studies will be carried out in support of these experiments and in other forefront areas including: Monte-Carlo shell model calculations, fusion reactions, pion interferometry, and coherent- and squeezed- state pion emission. Education of graduate students and postdocs is a strong component in every aspect of this umbrella grant to operate the Caltech Kellogg Laboratory. ***
