Polarization Transfer and the 3He(d,p)4He Reaction

9507202 Fletcher为了研究在极低能量下控制3he(d,p)4He反应的反应机理，我们将设计、建造和测试一个质子极化计，我们将用它来测量相关的极化传递系数。该装置将在纽约州立大学-Geneseo设计和制造，并使用Geneseo 2-MV范德格拉夫加速器的非偏振光束进行测试。偏振测量将在三角大学核实验室与北卡罗来纳大学教堂山分校的研究人员合作，使用原子束极化离子源进行。Geneseo的本科生将参与项目的所有阶段，从偏振计设计到数据分析。这个项目的结果将是第一次测量在3/2+共振附近的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反应和评价共振能量以下不同反应机制的重要性。＊＊＊

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. ***
