Experiments on the Quark Structure of the Nucleon

9307710巴顿-谢弗该奖项支持参加若干已获批准和提议的实验，这些实验将利用SLAC上的极化和未极化的电子束对准A终点站的目标。一项已获批准的实验预计将于1993年秋季进行，涉及22.6GeV的纵向极化电子和极化核子靶。这项实验(E143)将是美国第一个研究质子和中子与自旋相关的结构函数的深度非弹性散射实验；这些数据将被用来探索夸克对核子自旋的贡献(以阐明所谓的“自旋危机”)。***

9307710 Button-Shafer This award supports participation in several approved and proposed experiments which will utilize polarized and unpolarized electron beams at SLAC directed onto targets at End Station A. An approved experiment, anticipated for the fall of 1993, involves longitudinally polarized electrons at 22.6 GeV and polarized nucleon targets. This experiment (E143) will be the first deep-inelastic scattering experiment in the United States to study the spin-dependent structure functions of both proton and neutron; the data will be used to probe the quark contributions to nucleon spin (to elucidate the so-call "spin crisis"). ***
