9507202 Fletcher To study the reaction mechanism which governs the 3he(d,p)4He reaction at very low energies, we will design, construct, and test a proton polarimeter which we will use to measure relevant polarization transfer coefficients. The device will be designed and built at SUNY-Geneseo, and tested using unpolarized beams from the Geneseo 2-MV Van de Graaff accelerator. The polarization measurements will be made using the atomic beam polarized ion source at Triangle Universities Nuclear Lab, in collaboration with researchers from the University of North Carolina-Chapel Hill. Undergraduates students from Geneseo will be involved in all phases of the project, from polarimeter design to analysis of the data. The result of this project will be the first measurements of polarization transfer in the 3He(d,p)4He reaction near the 3/2+ resonance. These data will be useful in understanding the 3He(d,p)4He reaction and in evaluation the importance of different reaction mechanisms below the resonance energy. ***

9507202 Fletcher 为了研究在极低能量下控制 3he(d,p)4He 反应的反应机制，我们将设计、构建和测试质子旋光计，我们将用它来测量相关的偏振传递系数。 该设备将在 SUNY-Geneseo 设计和制造，并使用来自 Geneseo 2-MV Van de Graaff 加速器的非偏振光束进行测试。 偏振测量将与北卡罗来纳大学教堂山分校的研究人员合作，使用三角大学核实验室的原子束偏振离子源进行。 Geneseo 的本科生将参与该项目的所有阶段，从旋光计设计到数据分析。 该项目的结果将是首次测量 3/2+ 共振附近 3He(d,p)4He 反应中的极化转移。 这些数据将有助于理解 3He(d,p)4He 反应以及评估共振能量以下不同反应机制的重要性。 ***
