Experiments on the Quark Structure of the Nucleon

9307710按钮-Shafer 该奖项支持参与几个已批准和拟议的实验，这些实验将利用SLAC的极化和非极化电子束直接照射到终端站A的目标上。 一项预计于1993年秋季进行的核准实验涉及22.6 GeV的纵向极化电子和极化核子靶。 该实验（E143）将是美国第一个研究质子和中子自旋相关结构函数的深度非弹性散射实验;数据将用于探测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"). ***
