0072384PetratosThis is a proposal to investigate the internal structure anddynamics of the neutron and of the lightest nuclei in nature,deuterium and helium. The investigation will be based onexperimental studies of high energy electrons scattering offhydrogen and helium isotopes. The proposed research will use theelectron beam of the Jefferson Lab accelerator to bombard cryogenicdeuterium and helium targets and to study the nuclear reactionproducts with superconducting magnetic spectrometers. The resultsare expected to provide fundamental information on the distributionsof the three quark constituents of the neutron, the wave functionsof deuterium and helium and the interaction of the proton andneutron constituents of the two light nuclei.

这是一项研究中子和自然界中最轻的核--氢和氦--的内部结构和动力学的提议。这项研究将基于高能电子对氢和氦同位素的散射的实验研究。这项拟议的研究将使用杰斐逊实验室加速器的电子束轰击低温氚和氦靶，并用超导磁谱仪研究核反应产物。这些结果有望提供关于中子的三个夸克成分的分布、氢和氦的波函数以及两个轻核的质子和中子成分的相互作用的基本信息。
