Time Reversal, Neutron Structure and Neutron Beta Decay

9515418个Chupp实验将利用极化观测值来研究核子结构并探索粒子物理的标准模型。在SLAC上，将使用H、D和3He极化目标的深度非弹性电子散射来研究核子自旋结构。在MIT/Bates，在较低的能量下，准弹性电子散射将被用来测量极化的~3He中子的电形状因子。这些数据还将提供有关3He原子核结构的信息。作为标准模型的测试，将在NIST反应堆上研究极化中子的β衰变，以寻找违反时间反转不变性的情况。所有这些实验都具有很高的科学价值。在这些不同的活动中，密歇根小组将在偏振目标的发展和改进方面发挥特别重要的作用，特别是那些使用光泵技术的目标。这一发展是在密歇根州进行的，为学生提供了极好的培训和教育机会。除了光泵有几个应用方面，如核磁共振成像。***

9515418 Chupp Experiments will be carried out using polarization observables to study the nucleon structure and to probe the standard model of particle physics. The nucleon spin structure will be studied at SLAC using deep inelastic electron scattering from polarized targets of H, D, and 3He. At MIT/Bates at lower energy quasielastic electron scattering will be used to measure the electric form factor of the neutron using polarized 3He. These data will also provide information on the structure of the 3He nucleus. As a test of the standard model the beta decay of polarized neutrons will be studied at the NIST reactor to search for time reversal invariance violations. All of these experiments are of high scientific interest to the community. In these various activities the Michigan group will play an especially important role in the developments and improvements in the polarized targets, particularly those using optical pumping techniques. This development, carried out a Michigan, provides excellent training and educational opportunities for the students. In addition to optical pumping has several applied aspects, such as NMR imaging. ***
