This award provides support to investigate the internal structure anddynamics of the proton and neutron, and of the lightest nuclei innature: deuterium and helium. The investigation will be based onexperimental studies of high-energy electrons scattering off hydrogen,deuterium, tritium and helium nuclei. The proposed research will usethe high-intensity, high-energy electron beam of the Thomas JeffersonNational Accelerator Facility to bombard nuclei in cryogenic targetenvironments and to study the nuclear reaction products with particledetection devices using superconducting magnets and subatomic particledetectors. The results are expected to provide fundamental informationon the distributions of the three quarks inside the proton and neutron,on the quantum mechanical wave functions of deuterium and helium, and onthe mechanism of the interaction of the proton and neutron constituentsof these two light nuclei. The expected experimental data from theproposed investigation will offer valuable input to our understanding ofthe structure of the proton and neutron in terms of their three quarkconstituents and to the establishment of a consistent modern theorydescribing the simplest nuclear systems.

该奖项提供了研究质子和中子的内部结构和动力学的支持，以及最轻的核Innature：氘和氦气。 该研究将基于对氢，氘，trium和氦核散射的高能电子的一般研究。 拟议的研究将使用Thomas Jeffersonational Accelerator设施的高强度，高能电子束对低温靶环境中的轰击核，并使用超导磁体和亚原子颗粒电视机使用颗粒化设备研究核反应产物。预计结果将提供基本信息，即在质子和中子中的三个夸克，在氘和氦气的量子机械波函数上，以及质子与中子组成的相互作用的机理，这两个光核的相互作用机制。 来自规定的调查的预期实验数据将以我们对质子和中子的结构的理解，从其三种夸克统计以及建立一致的现代理论来为我们的理解提供了宝贵的意见。
